What can be said about the domain of the function f o g where f(y) = 4/(y-2) and g(x) = 5/(3X-1)? Express it in terms of a union of intervals of real numbers. Go to demos and obtain the graph of f, g and f o g.

Find the inverse of the function f(x) = 4 + sqrt(x-2).

State the domain and range of both the function and the inverse function in terms of intervals of real numbers. Go to demos and obtain the graph of f, its inverse, and g(x) = x in the same system of axes. About what pair (a,a) are (11,7) and (7,11) reflected about?
