Solve for the y–intercept for your function, f(x), and then construct a rough graph of your roller coaster. If your y–intercept is off the graph, give the coordinates of the y–intercept.
My function -- f(x)=x³+3x²-22x-24

@Mertsj  Can you please help me?? I don't know the steps for finding the y–intercept. I already have it graphed, so I know the y–intercept is (0,-24) and the x- intercepts are (-1,0), (-6,0), (4,0)...

mertsj · Answer

Find the y intercept by replacing x with 0.

mertsj · Answer

Because all points on the y axis have first coordinate 0

anonymous · Answer

which x?

mertsj · Answer

Every x
