We evaluate f (x) between [0, 2] We have then: f (x) = x2 + 2x +3 f (0) = (0) 2 + 2 (0) +3 = 3 f (1) = (1) 2 + 2 (1) +3 = 6 f (2) = (2) 2 + 2 (2) +3 = 11 We observe that the function g between [0, 2] is between 4 and 7 We observe that the function h is a linear equation whose rate of change is constant and equal to three. Answer: from least to greatest, by the rate of change of functions over the interval [0, 2] we have: g, h, f
