Question

If the factors of a quadratic function are (x + 2) and (x − 9), what are the x-intercepts of the function?

A.
(-9,0) and (-2,0)
B.
(-2,0) and (9,0)
C.
(2,0) and (9,0)
D.
(-9,0) and (2,0)

Answer 1

The correct answer is (-2,0) and (9,0)

Explanation:

PLATOOOOOOOOOOOO!!!!!!!!!!!!!!!

Answer 2

The x-intercepts of the function are:

• (-2,0) and (9,0)

Explanation:

As

`( x + 2 ) ( x - 9 ) = 0`

so

Either

( x + 2 ) = 0

or

( x - 9 ) = 0

solving ( x + 2 ) = 0

`x + 2 = 0`

`x = 0 - 2`

`x = -2`

solving ( x - 9 ) = 0

`x-9=0`

`x=9`

We also know that to get x-intercepts by setting y=0.

Therefore, the x-intercepts of the function are:

• (-2,0) and (9,0)
