Determine whether the function is onetoone. If it is, find itd inverse.
f(x)= 3x+4 over 5

For every x there is an f(x).
For every f(x) (which I'll call y) ther is an x.
y = (3x +4)/5
5y = 3x + 4
x = (5y 4)/3
The inverse function is
f^(1)(x) = (5x4)/3 
Use the functions f(x)=1/8x3 and
g(x)=x^3 to find the indicated value or function.
(g^1 X f^1)(3)
