Will give a which is true about the statements the graph of f(x) has a vertex of (–4, 6). the graph of f(x) is horizontally stretched. the graph of f(x) opens upward. the graph of f(x) has a domain of x < =–6.

B) The graph of f(x) is horizontally stretched.

Step-by-step explanation: We are given an absolute function .

The standard equation of an absolute function is .

Where (h,k) is the vertex of the absolute function.

If we compare and , we can see a=, h= -4 and h= -6.

Therefore, first, third and fourth options are incorrect.

So, the second option would only be applicable.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
