pav-90 [236]

Answer:

Average rate of change=-3

Step-by-step explanation:

The average rate of change is given by the relation between the values of f(x) and x, in two different points as follows:

$Change=\frac{f(x_{2})- f(x_{1})}{x_2-x_1}$

In this case, $x_{1}=-2; x_{2}=-1$

Therefore,

$Change=\frac{((-1)^{2}+10) -((-2)^{2}+10)}{-1-(-2)}=\frac{11-14}{1}=-3$
