Question 607435
Find the inverse function of f^-1(x). Give the domain of the inverse function.
a) f(X)=3x+4
f^-1(x) = (x-4)/3
Domain: All Real Numbers.
===================================
 b)f(x)=square root of x-4 
f^-1(x) = (x+4)^2 where x >=0
Domain: All Real Numbers >= 0
-----------------------------------

c) f(x)=1/x-2, x>2
x = 1/(y-2)
y-2 = 1/x
f^-1(x) = (1/x)+2 
Domain: All Real Numbers except x = 0
====================
