1. What can be said about the domain of the function fog where f(y) = y 2 and g(x) = 37 7? Express it in terms of a union of intervals of real numbers. Go to www.desmos.com/calculator and obtain the graph of f, 9, and fog. 2. Find the inverse of the function f (x) = 4 + vac - 2. 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 of f, its inverse, and g() = a in the same system of axes. About what pair (a, a) are (11, 7) and (7, 11) reflected about
