Use the linear approximation to estimate (-1.03){2}(3.01){2}. Compare with the value given by a calculator and compute the percentage error. 
a) 11.52; The percentage error is 2.15%. 
b) 11.21; The percentage error is 1.87%. 
c) 10.91; The percentage error is 1.62%. 
d) 11.45; The percentage error is 2.05%.
