average rate of change of

Question

find the average rate of change of each function on the interval specified.

y=1/x, on [1,3]

Answer 1

Average rate of change is an important concept in calculus, but calculating it requires only Algebra I math, namely the formula for slope between two points: m = (y₂ - y₁) / (x₂ - x₁).

So, find the y-values corresponding to x = 1 and x = 3 and divide their difference by the difference of the x-values, 2.
