Question

The function y=f(x) is graphed below. What is the average rate of change of the function f(x) on the interval −6≤x≤−5

Answer 1

`-4`

Step-by-step explanation

From Intervals x=-6 to x=-5

From the given graph;

`\begin{gathered} f(-6)=8 \\ f(-5)=4 \end{gathered}`

The average rate of change;

`\begin{gathered} (f(-6)-f(-5))/(-6-(-5)) \\ =(8-4)/(-1) \\ =(4)/(-1) \\ =-4 \end{gathered}`
