Question

PLEASE HELP MEEEEE!!!

Answer 1

Answer:

The rate of change of function A is greater than the rate of change of function B

Step-by-step explanation:

$\sf rate \ of \ change=\dfrac{change \ in \ y}{change \ in \ x}$

Function A

For every increase of 1 unit in x-values, the y-values increase by 3 units.

$\sf rate \ of \ change=\dfrac{3}{1}=3$

Function B

For every increase of 1 unit in x-values, the y-values increase by 2 units.

$\sf rate \ of \ change=\dfrac{2}{1}=2$

As 3 > 2, the rate of change of function A is greater than the rate of change of function B
