You are hired to count the number of ducks on three northern lakes during the summer. in the first lake, you estimate 500,000 ducks, in the second 250,000 ducks, and in the third 100,000 ducks. you write down that you have counted 850,000 ducks. as you drive away, you see 15 ducks fly in from the south and land on the third lake. do you change the number of ducks that you report? justify your answer.

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!
