Please help me with the second question …what is the average rate of change how do you know…it

Answer 1

7/3

2nd Question)

The average rate of change is defined as:

And this can be found by the following formula:

`\Delta=(f(b)-f(a))/(b-a)`

So let's pick two points and plug them into this formula, examining the given graph of that function:

Chosen Points: (2,6) and ( 0,-1)

`\begin{gathered} \Delta=(f(b)-f(a))/(b-a) \\ \Delta=(f(2)-f(0))/(2-(-1))=(6-(-1))/(2-(-1))=(7)/(3) \end{gathered}`

Hence, the average rate of this function is 7/3
