1. (3 pts.) i. Evaluate the polynomial p(x) = x - 7x + 8x +0.720 at a 0.535 using 4-digits arithmetic and chopping. Assume that you can only perform multiplication, subtraction, and addition. (No power raise is possible). How many arithmetic operations needed, and evaluate the relative percentage error. 1. ii. Repeat (i) but express p(x) as p(x) = ((x-7)x+8)x+0.720 How many arithmetic operations needed here? Evaluate the relative percentage error you get and compare with part (i).
