Answer:
Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function B has a greater rate of
Step-by-step explanation:
Function A:

Function B:

Required
Which has a greater rate of change
The rate of change of function A is calculated as thus:

Where:


So, we have:



For function B
The general function is:

Where
m is the rate of change
By comparing
to 

So, we have that:
Function A has a rate of -5; function B has a rate of -4.5.
By comparison: -4.5 is greater than 5
Hence, function B has a greater rate.
