which number is a zero of f(x) = 2x (x + 7) ( x-4)​

Answers

Answer 1

Answer:

0, -7, 4

Step-by-step explanation:

Zeros of a function are values that make the function = 0

So, f(x) = 2x(x + 7)(x - 4) = 0

                x = 0 or x + 7= 0  or x - 4 = 0

                                   x = -7           x = 4

Note:  If you were to graph f(x), the graph would intercept the x-axis at 0, -7, and 4
