What can be said about the domain of the functionf o g where f(y)=4/y-2andg(x)=5/3x-1? Express it in terms of a union of intervals of real numbers. Go towww.desmos.com/calculatorand obtain the graph off,g, andf o g.

2. Find the inverse of the functionf(x)=4+x2 .

3. State the domains and ranges of both the function and the inverse function in terms of intervals of real numbers. Go to www.desmos.com/calculator and obtain the graph off, g(x)=x its inverse, andin the same system of axes. About what pair (a, a) are (11, 7) and (7, 11) reflected about?
