Question

Which statement about y = x2 - 4x - 32 is true?A. The zeros are 8 and -4, because y = (x - 8)(x + 4).B. The zeros are 8 and -4, because y = (x+8)(x - 4).C. The zeros are -8 and 4, because y=(x - 8)(x+4).D.The zeros are -8 and 4, because y=(x+8)(x - 4).

Answer 1

Given the function:

$y=x^2-4x-32$

We must factor to find the roots of the equation, as follows:

$y=(x-8)(x+4)$

Hence,

ANSWER

A. The zeros are 8 and -4, because y = (x - 8)(x + 4)
