Answer:
5/7 gallons of water for each rose bush
Step-by-step explanation:
we know that
To find out the amount of water that Elena give to each rose bush, divide the total gallons of water by the number of rose bushes
so

therefore
5/7 gallons of water for each rose bush

Step-by-step explanation:
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]
![=\:\frac{\left[9\:-\:\frac{3}{2}\right]}{\left[3-\left(-1\right)\right]}](https://tex.z-dn.net/?f=%3D%5C%3A%5Cfrac%7B%5Cleft%5B9%5C%3A-%5C%3A%5Cfrac%7B3%7D%7B2%7D%5Cright%5D%7D%7B%5Cleft%5B3-%5Cleft%28-1%5Cright%29%5Cright%5D%7D)


Therefore, the average rate of change from x = -1 to x = 3 will be:
Average rate = 15/8
