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),](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F10c204a6-cb64-44c2-9d5a-9c6d90a911cf%2F36014a71-1c16-4ef2-9e3a-ed279dec62b5%2F7yvms6_processed.jpeg&w=3840&q=75)
