Question

Help?! Fan + Medal!

A polynomial function can be written as (x - 2)(x - 3)(x + 5). What are the x-intercepts of the graph of this function?

(2, 0), (3, 0), (-5, 0)
(-2, 0), (-3, 0), (5, 0)
(2, 0), (3, 0), (5, 0)
(-2, 0), (-3, 0), (-5, 0)

Answer 1

Set x - 2 = 0 and solve for x.
Do the same with the other factors, x - 3 and x + 5.

Answer 2

The y-coordinates are all 0.

Answer 3

Refer to the attached plot from Mathematica 9.
