Errors in approximations Suppose f(x) = Vr is to be ap- proximated near x = 8. Find the linear approximation to f at 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. Linear approx. Exact value Percent error 8.1 8.01 8.001 8.0001 7.9999 7.999 7.99 7.9
