What is the inverse of the function f(x)=2x+1

Alex drew a circle with right triangle prq inscribed in it, as shown below: the figure shows a circle with points p, q, and r on it forming an inscribed triangle. side pq is a chord through the center and angle r is a right angle. arc qr measures 80 degrees.

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function
