Answer:
, x>=0
Step-by-step explanation:

To find the inverse function , replace f(x) by y

Replace x with y and y with x

Solve the equation for y
take square root on both sides

Now subtract 6 from both sides

replace y with g(x)

Vertex is (-5,-10) y intercept of g is (0,-1) zeroes of h are x=-3,1
X+10=15
Isolate x by subtracting 10 from both sides
x+10-10=15-10
x=5
Final answer: B
Check by plugging the value in
5+10=15
True
