What is the average rate of change between

x=1 and x=2?

x=2 and x=3?

x=3 and x=4?

 The average rate of change between x = 1 to x = 2 is 2, from x = 2 to x = 3 is 4 and from x = 3 to x = 4 is 8.

Step-by-step explanation:  We are given to find the rate of change from

x = 1 to x = 2,  x = 2 to x = 3  and  x = 3 to x = 4.

We know that

The average rate of change between x = a to x = b for a function f(x) is given by

For the given function f(x), we have from the graph that

f(1) = 2,  f(2) = 4,  f(3) = 8  and  f(4) = 16.

So, the average rate of change from x = 1 to x = 2 is given by

The average rate of change from x = 2 to x = 3 is given by

The average rate of change from x = 3 to x = 4 is given by

Thus, the average rate of change between x = 1 to x = 2 is 2, from x = 2 to x = 3 is 4 and from x = 3 to x = 4 is 8.

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
