Average rate of change = change / interval

1) Function 1, h(x)

average rate of change = [h(2) - h(1)] / (2 - 1) = [3 - (- 3)]/1 = 6

2) Function 2, f(x)

average rate of change = [ f(2)  f(f)] / (2 - 1)

f(2) = (1/4)^2 + 4 = 1/16 + 4 = 4.0625

f(1) = (1/4)^1 + 4 = 1/4 + 4 = 4.25

average rate of change = [4.0625 - 4.25] / (2 - 1) = - 0.1875

3) Function 3

average rate of change = [0 - (-2)] / (2 -1).= 2

Therefore, function 2 has the lowest rate of change. < answer
