Plot the function approximation and the error function as shown in Fig. 2.59a

and b (p. 160) for the √x function for x ∈ [0.5, 1] using the following coefficients:

(a) For N = 2 use f(x)=0.4238 + 0.5815x = (108 + 149x)/256.

(b) For N = 3 use f(x)=0.3171 + 0.8801x − 0.1977x2 = (81 + 225x − 51x2)/256
