f(x) = x + 4
over the interval [4, 5]f(x) = 3x − 7
over the interval [-3, 7]f(x) = 9x + 1
over the interval [-5, -2]f(x) = 2x + 9
over the interval [1, 2]

Question

Arrange these functions from the least to the greatest value based on the average rate of change in the specified interval.
Tiles
f(x) = x + 4
over the interval [4, 5]f(x) = 3x − 7
over the interval [-3, 7]f(x) = 9x + 1
over the interval [-5, -2]f(x) = 2x + 9
over the interval [1, 2]

perl · Answer

the definition of average rate of change of f(x) over [a,b] is

[ f(b) - f(a) ] / (b-a)

perl · Answer

so for the first function
f(x) = x + 4 over the interval [4, 5]

[ f(5) - f(4) ] / (5- 4)
