C, i think you forgot an x
(x+11)+(x-7)
x+11+x-7
x+x+4
2x+4
Im sorry I know this is annoying but did you ever get an explanation on an answer?

Answer:
B. h(x) = (x -4)² -1
Step-by-step explanation:
The translation moved the vertex from (0, 0) to (4, -1). The vertex form equation is ...
h(x) = (x -h)² +k . . . . . quadratic with vertex (h, k)
Filling in the values of the vertex, we get ...
h(x) = (x -4)² -1
