Answer:
The average rate of change over the interval AC is 8
Step-by-step explanation:
To find the average rate of change, we divide the change in the output value by the change in the input value
The average rate of change over the interval AC is equal to
[tex]\frac{f(c)-f(a)}{c-a}[/tex]
In this problem we have
[tex]f(c)=f(2)=18[/tex]
[tex]f(a)=f(0)=2[/tex]
[tex]c=2[/tex]
[tex]a=0[/tex]
Substitute
[tex]\frac{18-2}{2-0}=8[/tex]
