Jse the linear approximation to estimate Af = f(3.1) - f(3) for f(x) = 10 1+ x 2 Use decimal notation. Give your answer to three decimal places.) Af ~ Estimate the actual change. (Use decimal notation. Give your answer to six decimal places.) Af = Compute the error and the percentage error in the linear approximation. (Use decimal notation. Give your answer to six decimal places.)
