the table shows the number of grapes eaten over several minutes. what is the rate of change for the function on the table? grapes eaten over time time in minutes (x) grapes eaten (y) 1 15 2 30 3 45 4 60 15 grapes eaten per minute 15 minutes to eat each grape 60 grapes eaten per minute 60 minutes to eat each grape
Answer
Answer:
A. 15 grapes eaten per minute
Explanation:
Step1: Recall rate - of - change formula
The rate of change of a function for a set of data points $(x_1,y_1)$ and $(x_2,y_2)$ is $\frac{y_2 - y_1}{x_2 - x_1}$.
Step2: Select two points
Let's take $(x_1,y_1)=(1,15)$ and $(x_2,y_2)=(2,30)$.
Step3: Calculate rate of change
$\frac{y_2 - y_1}{x_2 - x_1}=\frac{30 - 15}{2 - 1}=\frac{15}{1}=15$. This means 15 grapes are eaten per minute.
