Suppose we want to estimate f'(4) for f(x) = 8|og(x) using a difference quotient with h > 0 . From the graph of f(x) , would you expect your estimate to be greater than or less than f'(4) ? O The estimate should be less than the actual value because the slope of the secant line is greater than the slope of the tangent line. 0 The estimate should be less than the actual value because the slope of the secant line is smaller than the slope of the tangent line. 0 The estimate should be greater than the actual value because the slope of the secant line is smaller than the slope of the tangent line. 0 The estimate should be greater than the actual value because the slope of the secant line is greater than the slope of the tangent line
