Question

The table shows the amount of pet food in cups remaining in an automatic feeder as a function of the number of meals the feeder has dispensed. Based on the table, which function models this situation?f(n)= −3n + 24f(n)=−1/3n+16f(n)= −3n+64f(n)=−1/3n+8

Answer 1

Let's check it out

If f(n) = -3n + 24

if n=1

f(1) = -3(1) + 24

=21

if n=3

f(3) = -3(3) + 24

=-9+ 24

=15

If n=6

f(6) = -3(6) + 24

=-18 + 24

=6

Hence the function that models the situation is f(n) = -3n +24
