Add a grid (b) Approximate the value ofy when x - 15 using linear and spline interpolations. (c) Approximate the value of x when y -80 using linear and pchip interpolations (d) Use cubic spline interpolation to approximate y-values for x-values evenly spaced between 10 and 100 at intervals of 2. Overlay this interpolation on the data obtained in (a). Add appropriate legend
