The graph of which function is decreasing over the interval (–4, ∞)? f(x) = (x + 4)2 + 4 f(x) = –(x + 4)2 + 4 f(x) = (x – 4)2 – 4 f(x) = –(x – 4)2 – 4

Step-by-step explanation:

The second option is .

This function is of the form, , where is the vertex.

This is a maximum graph because .

The vertex of this function is .

Since it is a maximum graph,the function increases on the interval and decreases  on the interval .

The correct answer is B.
