Answer:
54
Step-by-step explanation:
I hope that this helps you!
The domain of the inverse of a function is the range of the original function
so find the range of f(x)
this is lowest to highest
we got the vertex is at (0,4)
and it goes to infinity
so range is from 4 to infinity
inverse
replace f(x) with y
switch x and y
solve for y
replace y with finverse
f(x)=x^2+4
y=x^2+4
x=y^2+4
x-4=y^2
y=√(x-4)
f⁻¹(x)=√(x-4)
inverse is f⁻¹(x)=√(x-4)
the domain is x≥4
