1. Find the inverse of F(x)=1/3x+1/3 Graph the original function and its inverse on the same coordinate plane. You must show your work in order to receive all 10 points (including the original graph and its inverse, line of symmetry and how you found the inverse).
2. The function a(t)=15t+10 gives the amount "a" (in dollars) you pay to rent a jet ski for a base fee of $10 and use it for "t" hours. Write and interpret the inverse of this function. Please show your work for full credit
3. let F(x) =log3x, find f(81)
