EX #7: Letfbe a function that is differentiable for all real numbers. The table below gives the values of f(x) and its derivative f'(x) for selected values in the interval [ 1.0, 1.0]. The function is concave up in this closed interval. A. Write an equation ofthe line tangent to the graph off(x) wherex = 0.6. B. Use this line to approximate the value off( 0.5). C. Is this approximation greater or less than the actual value off( 0.5) and give a reason
