Question

Which of the following is a zero for the function f(x) = (x + 3)(x - 7)(x + 5)

O x= -7
x = -3
x = 3
x = 5

Answer 1

-3, 7, -5

Explanation:

The x intercept is when y equals zero, so plug in numbers that would make y equal 0.

In this case, if anything inside the brackets is 0 then the whole think would be 0.

any number times 0 is 0.

Hope this helps!
