A function and its inverse function? The function f(x)= x+1 is one-to-one for x? > ? 1 and has an inverse on that interval. a.? Graph ?f? for ?x? > ?1. ?1 b.? Find the inverse function f corresponding to the function graphed in part (a). Graph f ?1 on the same set of axes as in part (a). ?1 c.? Evaluate the derivative of f ? t the point . ?1 d.? Sketch the tangent lines on the graphs of ?f? and f at and , respectively.

Solution Step 1: Given f(x)= x x+1
