(b) Use cubic interpolation of x versus y or f (x). Compute the true percent relative error. (c) Use inverse interpolation with quadratic interpolation and the quadratic formula. Compute the true percent relative error. (d) Use inverse interpolation with cubic interpolation and bisection. Compute the true percent relative error. (e) Compare the results from (b), (c), and (d) and comment on your findings.
