Question

What are the zeros of f(x) = (x -7)(x − 3)(x - 2)?

A. 7,-3,2
B.7,-3, -2 C.7,3,2
D.7,3,-2

Answer 1

Explanation:

that is really easy, when you have the function in such a factorial form already.

the zeros of the whole function are the x values that turn at least one factor to 0 (as when one factor is 0, then the whole expression is 0).

so, you get a zero, when x = 7, or x = 3, or x = 2.

because then either x-7 or x-3 or x-2 is 0.

therefore, C is the right answer.
