Errors in approximations Suppose is to be approximated near ? x = 8. Find the linear approximat?ion t?o f ? at ?x = 8. Then, complete the following table, showing the errors in various approximations. Use a calculator to obtain the exact values. The percent error is 100 • | approximation - exact | / | exact |. Comment on the behavior of the errors as ?x approaches 8.

SOLUTION STEP 1 .The linear approximation formula is given by y = L(x) = f(a)+f (a)(xa) Given f(x) = and a = 8. 3 f(a) = 8 = 2 Then f (x) = 12 (a) = 12 = 1 3x3 3(8) 12 Therefore 1 L(x) = 2+ (128) x Linear Exact Percent approx value error 8.1 2.0083 2.0082 0.00497 8.0 2.000833 2.0008 0.00016...
