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.

Step-by-step explanation:
percent increase = (new number - original number) / (original number) * 100
= (1200 - 840) / (840) * 100
= (360) / 840 * 100
= 0.4285 * 100
= 42.85% rounded to nearest percent = 43% <==
