Hi there looking for help to understand these questions

(a) Consider NV equispaced points on the interval 0 2. The blue curve is the underlying function and the red curve is the piecewise linear interpolation polynomial for the value of h given by the formula in the answer to (a). N = 090 (c) Use the polynomial interpolation error theorem to write down an exact expression for the error e] (a) = f(a) - P1 (a) on the subinterval x ;
