Question

Consider the following function

g(x)=√x-7

Which of the following represents the domain and range of g^-1 (x)?

Answer 1

For g(x) = √(x-7), the domain is [7, ∞) and the range is [0, ∞).

For g^-1(x), the domain is the same as the range of g(x) and the range of g^-1(x) is the same as the domain of g(x).
