Answer:
D
Explanation:
A and B would move the functional graph unchanged 6 units up and down.
but that is clearly not what happened.
so, A and B are out.
h(x) is instead f(x) shifted 6 units to the left.
that means the functional value h(x) is the same as f(x') just 6 units "earlier". that means x = x' - 6 or x' = x + 6.
therefore,
h(x) = f(x + 6) = sqrt(x + 6)
