text: If a > 0, it opens to the right.
text: If a < 0, it opens to the left.
text: We can easily identify that the parabola is opening left or right.
text: For the parabola to open to the left or right, you need this equation:
text: This shows that if p > 0 that is, p is positive then the parabola opens towards right and if p < 0 that is, p is negative then the parabola opens towards left.
text: Based on what we know without plugging anything in, we can say that the parabola will be opening up to the left because its focus is to the left of the origin.
text: Hence, the parabola opens towards the right.
text: If the parabola opens to the right or to the left with a directrix of x = h-p,
text: Assume that the vertex of the parabolic mirror is the origin of the coordinate plane, and that the parabola opens to the right (i.e., has the x-axis as its axis of symmetry).
text: Assume that the vertex of the parabolic mirror is the origin of the coordinate plane, and that the parabola opens to the right (i.e., has the x-axis as its axis of symmetry).
text: = k. If p > 0, the parabola opens to the right, and if p < 0, the parabola opens to the left.
text: $(y-k)^2 = 4p(x-h) $ if $p$ is positive the parabola opens to the right, if $p$ negative parabola opens to the left.
text: Since the coefficient in front of the x term is positive, we can say that the parabola will open to the right.
text: Assume that the vertex of the parabolic mirror is the origin of the coordinate plane, and that the parabola opens to the right (i.e., has the x-axis as its axis of symmetry).
text: Since a < 0 and the parabola opens horizontally, this parabola opens to the left (see Figure 3).
text: = k. If p > 0, the parabola opens to the right, and if p < 0, the parabola opens to the left.
text: For the parabola to open to the left or right, you need this equation:
text: From here we can say that the parabola will open to the left.
text: The equation 4a(x-h)=(y-k)2 generates a parabola which opens to the right if a>0 and opens to the left if a<0.
text: If p < 0, the focus is to the left of the vertex and the parabola opens to the left.
text: Please observe that this is "x" as a function or "y" which means that the parabola opens either left or right (instead of up or down).
