For the function
Sketch the graph and the inverse.
First, graph the function. Then, reflect the graph across
y = x.
Find the equation of the inverse function.
Replace f(x) with y, then switch the variables.
Now solve for y.
Do not forget to replace y with
Determine the domain and range of the inverse.
See graph in part (a).
for in the function . Now substitute the answer you found for for in the inverse function
