Answer:

B) h(x) = -1/4(x - 6)(x + 3)

Step-by-step explanation:

Zeros of a function:

Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.

In this question:

Concave down, so [tex]a < 0[/tex], which excludes options c and d.

Roots at x = 6 and x = -3. So

[tex]-\frac{1}{4}(x-6)(x-(-3)) = -\frac{1}{4}(x-6)(x+3)[/tex]

So option B.
