Need with algebra these functions from the greatest to the least value based on the average rate of change in the specified interval. need the answers asap

We know that the average rate of function f(x) from x=a to x=b i.e. in the interval [a,b] is calculated as follows:

a)

interval: [-2,3]

We have:

and

The average rate of change is calculated as:

Hence, Average rate of change is: 4

b)

interval: [4,5]

and

The average rate of change is calculated as:

Hence, Average rate of change is: 3

c)

interval : [-3,4]

The average rate of change is calculated as:

Hence, Average rate of change is: -1

d)

interval : [-1,1]

and

The average rate of change is calculated as:

Hence, Average rate of change is: 0

Hence, on arranging the functions from greatest to least value based on average rate of change in the specified interval is:

i.e.   a < b < d < c

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
