Question: how to find x and y intercepts in a rational function?
Answer: To find the y-intercept(s) (the point where the graph crosses the y-axis), substitute in 0 for x and solve for y or f(x). To find the x-intercept(s) (the point where the graph crosses the x-axis â€“ also known as zeros), substitute in 0 for y and solve for x. Examples: Find the intercepts of the function given.
