Given: f(x) = x 2, g(x) = x + 6, h(x) = 7

find h{g[f(x)] }.

a. 7
b. 20
c. 55

The graph of the function f(x) = (x + 2)(x + 6) is shown below. which statement about the function is true? the function is positive for all real values of x where x > –4. the function is negative for all real values of x where –6 < x < –2. the function is positive for all real values of x where x < –6 or x > –3. the function is negative for all real values of x where x < –2.
