In total there are 5 kids so
5÷3.5=1.4
(rounded)
Using it's concept, the rate of change between point C and point D is of 2.
<h3>What is the average rate of change of a function?</h3>
The average rate of change of a function is given by the <u>change in the output divided by the change in the input</u>. Hence, over an interval [a,b], the rate is given as follows:

Considering the points of the given linear function, we have that:
Hence the rate of change between point C and point D is given by:
r = (4 - 2)/(2 - 1) = 2.

I think the answer would be C to this problem
Answer:
11.8 in.
Step-by-step explanation:
Answer:
[0,9]
Step-by-step explanation:
The domain is the first set of the ordered pair. When finding the domain you are supposed to find which x value it starts from to where it ends. The x value starts from 0 and ends and the 9th unit on the x-axis which would give us 0,9 now since both points are closed you would use these symbols [ ] to show that it is closed meaning the answer would be [0,9]
Note:
I'm sorry if this is wrong but this is what I believe the answer is.
