Homework Statement
The function f:x→ 4-x2 for the domain x≤0. Find the inverse of is denoted by f-1 and state the domain and range of f-1.
Homework Equations
Set equation to 0 and solve for x to find inverse. The D and R is going to be switched for the inverse..?
The Attempt at a Solution
I think I have found the inverse and range for this problem:
f-1(x) = -√4-x
and has a range of y≤0 (which was given in problem)
not sure of range. Are my solutions correct?
