Solve for x in each set of parentheses by setting them to 0:

X -8 = 0

X = 8

X+9 = 0

X =-9

You have two x intercepts (8,0) and (-9,0)

You didn’t list any choices to pick from but it would be either if the ones above.

The function can be written like f(x) = (x - 8)(x + 9).

Solve for the zero for both parts of the function.

0 = x - 8

0 + 8 = x - 8 + 8

8 = x

0 = x + 9

0 - 9 = x + 9 - 9

-9 = x

Therefore, the x-intercepts are (8, 0) and (-9, 0).

Best of Luck!
