Atiger in captivity is fed 13.5 pounds of food an elephant in captivity eats per day. compare the function by comparing their rates of change.

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
 SEE ATTACHED IMAGE.
 The first thing that we are going to do in this case is to find the slope of the line for the function that simulates the amount of food of the elephant.
 We have then:
 m = (y2-y1) / (x2-x1)
 Substituting any two points:
 m = (625-125) / (5-1)
 m = 125 pounds / day
 125> 13.5
 
 The elephant eats more than the tiger daily.
