Answer:
Function 2 is changing more rapidly
Step-by-step explanation:
We need to find the slope of each function to determine which one is changing more rapidly
m = (y2-y1)/(x2-x1)
Function1
(0,20) and (5,0)
m = (0-20)/(5-0)
= -20/5
= -4
Function 2
(2,11) and (4,2)
m = (2-11)/(4-2)
= -9/2
= -4.5
We do not care about the sign, just the number when we determine which one is changing more rapidly. The sign tells the direction, the number tells the rate.
|-4| < |-4.5|
4 < 4.5
Function 2 is changing more rapidly
