Find the inverse of f(x)= 2tan(x - 1) + 3.
Interchange x and y; then solve for "y":
x = 2tan(y-1)+3
(x-3)/2 = tan(y-1)
----
y-1 = arctan[(x-3)/2]
---
f^-1(x) = arctan[(x-3)/2]+1
----
Domain of f^-1: All Real Numbers
Range of f^-1: All Real Numbers
-----------------------------------------
f(x) = 2*tan(x-1)+3
Domain: All Real Numbers
Range: All Real Numbers
