Answer:

Average rate of change(A(x)) of f(x) over the interval [a, b] is given by:


A(x) = (f(b)-f(a))/(b-a)

As per the statement:

From the given graph as shown :

At x = -2

then;

f(-2) = -1

At x = 0

then;

f(0) = -1

To find the average rate of change for the given graph from x = –2 to x = 0 .

Substitute the given values we have;


A(x) = (f(0)-f(-2))/(0+2)


A(x) = (-1-(-1))/(2)


A(x) = (-1+1)/(2)


A(x) =0

Therefore, the average rate of change for the given graph from x = –2 to x = 0 is, 0

For this case we have to find the average rate of change of a parabola in the interval from
x = -2 to
x = 0. To do this, we need two points for the parabola pass, and apply the following formula:


AVR = \frac {f (x_ {2}) - f (x_ {1})} {x_ {2} -x_ {1}}

We have the following points, taking into account that
y = f (x):


(x_ {1}, f (x_ {1})) = (- 2, -1)\\(x_ {2}, f (x_ {2})) = (0, -1)

Substituting:


AVR = \frac {-1 - (- 1)} {0 - (- 2)}\\AVR = \frac {-1 + 1} {0 + 2}\\AVR = 0

So, the average rate of change for the given graph is 0 in the given interval

Answer:


AVR = 0\ from\ x = -2\ to\ x = 0
