The degree (or "order") of a polynomial is simply the largest exponent value in the expression. If the degree of your polynomial is 2 (there is no exponent larger than x2), you can find the axis of symmetry using the formula method above. If the degree of the polynomial is higher than 2, use this graphical method. Make two lines in the shape of a plus sign. The horizontal line is your x-axis; the vertical line is your y-axis. Mark both axes with numbers at equal intervals. Spacing should be uniform on both axes. Take your polynomial or function and calculate values of f(x) by putting all values of x into it. You now have pairs of y = f(x) for every x on the axis. For each (x, y) pair, make a point on the graph vertically on the x-axis and horizontally on the y-axis. Once you have marked all the graph points, you can connect your dots smoothly to reveal a continuous graph of your polynomial. Inspect your graph carefully. Look for a point on the axis such that when a line is passed through it, the graph splits into two equal, mirrored halves. If you can find a point call it "b" on the x-axis that splits the graph into two mirrored halves, then that point, b, is your axis of symmetry.

Look through your basementor the lowest level of your houseto find where the main sewer line passes into the earth outside. The main sewer line carries all sewage leaving your house directly to the septic tank. The main sewer line is typically made from cast iron or heavy PVC pipe. Once you've noted where the sewer line leaves your house, find the corresponding point on the outside of your home. The sewer line will continue underfoot for several feet, until it empties its contents into the septic tank. So, since sewer lines run straight, you can be confident that the septic tank lies in a straight line from the point where the sewer line exits your house. Septic tanks are commonly located within 10 feet (3.0m) of your home, in the front or back yard. After the septic tank was installed (when your home was first built), the dirt and soil on top of the tank may have sunk below the level of the surrounding ground. Walk outwards from your home following the direction of the sewer line, and note any areas that have settled or which are covered with dead grass or extra-wet soil. Since it's easier to let sewage flow downhill than to pump it uphill, the settled area will typically be downhill from your home. Grass above your septic tank may be dead and brown because, if the tank is not buried very deep, it will keep grass roots from growing far into the soil. Similarly, the surface of the ground above your septic tank may become saturated since water is not able to drain far down into the soil.

Spider mites are attracted to many plants, including indoor and outdoor, with some of those being strawberries, melons, beans, tomatoes, eggplant, pea pods, ornamental flowers, trees, and most houseplants. When checking for spider mites, you'll be able to identify plants they have infested by the state of the plant. Spider mites suck the sap from the plant, which causes damage to its leaves. Some noticeable signs of spider mites are: Yellow, tan, or white spots on the leaves Very small white or red spots on the leaves that move (these are the spider mites) White, cottony webbing that appears on the underside of the leaves Eventually leaves may curl up after changing color and fall off Before you begin treating spider mites, it's good to be familiar with what they look like and the harm they cause. If you are unable to see them on the leaf, hold the stem of your plant over white paper and gently shake, causing the spider mites to fall on the paper. Spider mites are very small, so they can be difficult to see, but with a magnifying glass you will be able to make out a small body with eight legs, and a red, brown, yellow, or green coloring. Spider mites are most common in hot, dry and dusty conditions and most prevalent in places where they have no predators, such as plants that have been treated with insecticide.

When you use your wok for steaming, you need to add a basket or rack to hold the food above the water. The concave shape of the wok makes it ideal for holding a bamboo steamer basket insert that is traditional in Chinese cooking. A metal steaming rack can work well too, though. Place the vegetables, dumplings, or other food that you're steaming in a single layer in the basket or rack, so they'll all be steamed evenly. The benefit to using a bamboo steamer basket is that its lid actually absorbs excess moisture inside the wok, so it doesn't drip back down over the food and make it soggy. If you are using a metal steaming rack, you can opt for a style that has hooks to secure it over the edge of the wok or one that has legs that will hold it above the water in the bottom of the wok. If you're using a bamboo basket to steam food in your wok, you should line the bottom to prevent the ingredients from sticking to it. You can use cabbage or lettuce leaves, or parchment paper to line the basket. A bamboo steamer basket has its own lid to trap the steam, but if you're using a metal rack, you'll need to place the lid on top of the wok. Before placing the steamer basket or rack inside, you should add water to the wok and bring it to a boil. You'll want to fill the wok with approximately 2-inches of water, though it vary depending on how large your wok is. The water level should be about halfway up to the bottom of the steamer basket or rack. Turn the heat up high to bring the water to a boil. Before you bring the water to a boil, make sure that the steamer basket or rack fits securely in the wok and isn't going to tip over. Remove it before you boil the water, though. The food in your steamer basket or on the rack should sit above the water, so it doesn't get overcooked. You don't have to use water to steam in your wok. Any translucent, light liquid, such as broth, stock, wine, or juice, can work. Once the water has come to a boil, reduce the heat to keep it a simmer and place the steamer basket inside the wok. You should keep an eye on the water level because if too much water evaporates, you may need to add more to properly steam the food. Check on the food every few minutes to determine if it's done to your liking and remove it from the basket or rack. The steam inside a wok is extremely hot, so be sure to use long-handled tongs when you're adding and removing food to prevent burns. After using your wok for steaming, there may be a waterline across the surface. You'll need to re-season the wok to get rid of it.
