(1 point) The figure below shows f(x) and its local linearization at x = a, y = 2x - 5. (The local linearization is shown in blue.) What is the value of a? a = What is the value of f(a)? f(a) = 2 Use the linearization to approximate the value of f(2.4). f(2.4) = Is the approximation an under- or overestimate? (Enter under or over.)
