we can calculate the average rate of change using this formula
[tex]\frac{f(x_2)-f(x_1)}{x2-x1}[/tex]
where x2 is 7 and f(x2) is the corresponfing value, 17
x1 is 1 and f(x1) is 95, then replacing
[tex]\begin{gathered} \frac{17-95}{7-1} \\ \\ \frac{-78}{6} \\ \\ =-13 \end{gathered}[/tex]
the rate of change is -13
