Question

The figure shows how a function f(x) and its linear approximation (i.e., its tangent line) change value when x changes from x0 to x0 + dx. Suppose f(x) = x^2 - 6x, x0 = 3 and dx = 0.05. Your answers below need to be very precise, so use many decimal places. (a) Find the change ?f = f(x0 + dx) – f(x0). ?f = (b) Find the estimate (i.e., the differential) df = f'(x0) dx. df = (c) Find the approximation error | ?f – df |. Error =
