Twelve cans of peaches are placed into each box. write a function rule for the number of boxes needed for c cans. how many boxes are needed for 1440 cans

C = # of cans

b = # of boxes                          

C  |  B    

12 |  1

24 | 2

36 | 3

12b = C

12b/12 = 1440/12

b = 120 boxes

for 1440 cans.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
