please help with these questions on linearization:

(actual value)*( approximated value) 3. (% error) = (actualvalue) X 100% Use the formula above to nd the answer to the following question: . . . _ 3:2 +1n(:r) _ . If the local hnear approx1matlon of f (at) 3 at x2 18 used to nd the approximation for f (2.2), then the % error of this approximation is... O less than 2%. O between 2% and 5%. 0 between 5% and 8%. 0 between 8% and 11%. 0 between 11% and 14%. (actual value)(appr0ximated value) 4. (% error) = (actualvalue) X 100% Use the formula above to nd the answer to the following question: If the local linear approximation of f (at) = 3 sin a". | 63"" at x=2 is used to nd the approximation for f (1.9), then the % error of this approximation is... O Between 2% and 4% 0 Between 4% and 6% 0 Between 6% and 8% 0 Between 8% and 10% O Greater than 10%
