Please I need help with question 49. Thank you

4.8 The derivative of f(x) = 1/(1 – 3x) is given by %3D 6x (1 – 3x)? | Do you expect to have difficulties evaluating this function at x = 0.577? Try it using 3- and 4-digit arithmetic with chopping. 4.9 (a) Evaluate the polynomial y=x' – 7x + 8x – 0.35 at x = 1.37. Use 3-digit arithmetic with chopping. Evaluate the percent relative error. (b) Repeat (a) but ex press y as y= ((x– 7)x + 8)x – 0.35 Evaluate the error and compare with part (a),
