Find the range of the following function.

f(x) = (4+x)/(3-2x)

Looking for something like this

y= x^2
x = +/- sqrt(y)

y>0

range of will be the domain of



swap variables ...



solve for ...









domain of the inverse function is all reals except

so ... range of is all reals except

thanks so much
