Question

If f(x) = −2(x + 3)(x + 5), complete the square and determine the minimum or maximum value of the function.

A) f(x) = (x + 4)2 + 2 and f(x) has a maximum value f(4) = 2.
B) f(x) = −2(x + 4)2 + 2 and f(x) has a minimum value f(4) = 2.
C) f(x) = (x + 4)2 + 2 and f(x) has a minimum value f(−4) = 2.
D) f(x) = −2(x + 4)2 + 2 and f(x) has a maximum value f(−4) = 2.
