see graph.

Domain of both functions is

Range of both functions is

#### Explanation:

a = vertical stretch

so your equation:

a = 7

b = 1

c = 0

d = 0

so your graph will be the parent

Domain of both functions is

Range of both functions is

here is the parent graph:

graph{sqrtx [-10, 10, -5, 5]}

And here is yours:

graph{7sqrtx [-9.96, 10.04, -0.52, 9.48]}
