Rebecca's ERROR
Rebecca wrongly used the formula to calculate the average rate of change from x = -1 to x = 3.
She should have used the correct formula to calculate the average rate of change from x = -1 to x = 3 which is:
Average rate = [f(3) - f(-1)] / [3 - (-1)]
But, she reversed the formula.
The correct solution
Considering the graph
Rebecca wants to find the average rate of change from x = -1 to x = 3.
so
at x₁ = -1
at x₂ = 3
Using the formula, we can determine the average rate of change from x = -1 to x = 3
Average rate = [f(3) - f(-1)] / [ x₂ - x₁]
Therefore, the average rate of change from x = -1 to x = 3 will be:
Average rate = 15/8
