Suppose we are using piecewise polynomials to approximate the underlying function f(x) = using equally- spaced nodes over the domain [0.5,3]. (a) Assume piecewise linear interpolation is used. Estimate the number of subintervals required so that the error is bounded by 10-2. Use matlab plot to confirm your calculation. (b) Suppose piecewise quadratic interpolation is used. Estimate the number of subintervals required so that the error is bounded by 10-³.
