Find the domain and range of the inverse of the given function.
f(x)=x^2-7; x>= 0
graph%28400%2C300%2C0%2C20%2C-10%2C20%2Cx%5E2-7%29
Domain: x>=0
Range: y>=-7
----------------------
Inverse:
x = y^2-7
y = sqrt(x+7); x>=0
graph%28400%2C300%2C-10%2C20%2C-10%2C20%2Csqrt%28x%2B7%29%29
Domain: x>=-7
Range: y>=0
