Question

The zeros of a quadratic function are 6 and -4. Which of these choices could be the function? A. f(x) = (x − 6)(x + 4) B. f(x) = (x − 6)(x − 4) C. f(x) = (x + 6)(x − 4) D. f(x) = (x + 6)(x + 4)

Answer 1

A.) f(x)=(x-6)(x+4)

Step-by-step explanation: I got it right on the test, hope this helps!

Answer 2

A. f(x) = (x − 6)(x + 4)

Explanation:

Zeros of the equation are the points where f(x) = 0

If x = 6 is a zero,

Factor is (x - 6)

If x = -4 is a zero,

Factor is (x + 4)

The function should be of the form:

f(x) = A(x - 6)(x + 4)

From the options, it's

f(x) = (x - 6)(x + 4)
