HOMEWORK QUESTION 2
Following number 1 above, find the average rate of change between x=2 and x=0 for the function f.
-2
ROC = change in output / change in input
-4-0/2-0 = -4/2 = -2

HW #5A: Is the relationship between the time and ants linear? Describe why or why not?
NO! rate of change is NOT constant
(x)(10-2x)(5-2x)
4x3-30x2+50x
HOMEWORK QUESTION #4 A & B
A. Determine if the relationship between the time and ants is or is not linear. Describe your reasoning.
B. If it is linear then write the rule for function, call it A(t)
A. LINEAR - constant rate of change
B. A(t) = 140 + 20(n-1)
remember! A(t)=A(1) + ROC(n-1)
or Y=20x + 120
