HELP ITS ABOUT FUNCTIONS Explanation needed

Answer:
Function B has a greater rate of change since it has a greater slope
Step-by-step explanation:
The slope for function A
m= (y2-y1)/(x2-x1)
= (15-13)/(6-5)
= 2/1
=2
The slope for function B
We have 2 points ( (1,1) and (2,4)
m= (y2-y1)/(x2-x1)
= (4-1)/(2-1)
=3/1
=3
Function B has a greater rate of change since it has a greater slope
Answer:
B
Step-by-step explanation:
The slope for function A = (15 - 13) / (6 - 5)
= 2
The slope for function B = (4 - 1) / (2 - 1)
= 3
B has a bigger slope, so it has greater rate of change.
Hope this helps!
