suppose f(x)=√x+1
a. what are the domain and range of f?
b. find f^-1(x). what are its domain and range?
c. show that (fof^-1)(a)=a=(f^-1of)(a) for any a in the respective domains
d. solve the equation f(x)=f^-1(x). remember to check for extraneous roots
e. graph the functions f and f^-1. be sure that you accurately represent the domains of each function. interpret graphically the solutions you found to the equation in part (d).
