Question

# 1. What can be said about the domain of the function $f∘g$ where $f(y)=y−24 $ and $g(x)=3x−15 $ ? Express it in terms of a union of intervals of real numbers. Go to www.desmos.com/calculator and obtain the graph of $f,g,$ and $f∘g.$

2. Find the inverse of the function $f(x)=4+x−2 .$

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 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?
