Question

Find all x-intercepts and y-intercepts of the graph of the function.
F(x)= x^3 - x^2 -9x +9

Answer 1

x= (3,0),(-3,0),(1,0)
y= (0,9)

Answer 2

find the y-intercept by putting x = 0 in your function

Answer 3

That comes out to 9 right?

Answer 4

twigo2 - dont just give him the answer - show him how to solve the problem

Answer 5

yes so y-intercept is the point (0.9)

Answer 6

(0,9)

Answer 7

Okay thanks, I'm just not sure how to find the x intercept if there If there is no y value

Answer 8

Woops sorry for my wording.

Answer 9

you need to solve the equation

x^3 - x^2 - 9x + 9 = 0

Answer 10

Oh I see, I got it!

Answer 11

Thank you!

Answer 12

one clue to this is since the last number is + 9
so x = 3 and x = -3 are possible values of the intercepts
