Question: how to find x and y intercepts of a curve?
Answer: Since a point on the y axis has x coordinate equal to zero, to find the y interecpt, we set x to zero and find the y coordinate which is f(0). ... 
A point on the x axis has y coordinate equal to 0, to find the x intercept, we set y = f(x) = 0 and solve for x. ... 
Solve for x.
