Answer:
The average rate of change of the function
over the interval
is -1
Step-by-step explanation:
We are given the function
over the interval 
We need to find average rate of change.
The formula used to find average rate of change is : 
We have b=-1 and a=-11
Finding g(b) = g(-1)

Finding g(a) = g(-11)

Finding average rate of change

So, the average rate of change of the function
over the interval
is -1
The square on the hypotenuse is skew and impossible to visually validate. There's nothing to sum. It is a simple calculation to note that <span><span><span>32</span>+<span>42</span>=<span>52</span></span><span><span>32</span>+<span>42</span>=<span>52</span></span></span><span>, but its picture doesn't 'say' that the angle between the 3 and 4 sided square must be 90 degrees.
