Question 77634
Find the inverse of each function.  Is the inverse a function?
f(x) = (x-1)^2 + 3
----------
Interchange x and y to get:
x=(y-1)^2+3
Solve for y to get the inverse:
(y-1)^2=-x-3
y-1 = sqrt(-x-3) or y-1 = -sqrt(-x-1)
y = 1 + sqrt(-x-3) or y = 1-sqrt(-x-1)
The inverse is not a function because there are two y values of each value in the Domain.
