Answer:

The x-intercepts of the function are:

  • (-2,0) and (9,0)

Step-by-step explanation:

As

[tex]( x + 2 ) ( x - 9 ) = 0[/tex]

so

Either

( x + 2 ) = 0

or  

( x - 9 ) = 0

solving ( x + 2 ) = 0

[tex]x + 2 = 0[/tex]

[tex]x = 0 - 2[/tex]

[tex]x = -2[/tex]

solving ( x - 9 ) = 0

[tex]x-9=0[/tex]

[tex]x=9[/tex]

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)
