Castaways, we are castaways Ahoy there, ahoy, we are castaways
We're stuck where we are
With no house, no car
Castaways, ahoy, we are castaways
We were out at sea on a sailing ship
The rain began to rain, and the wind began to whip
We felt the ship tip, it was going down
So we launched our lifeboat, so we wouldn't drown
Castaways, we are castaways
Ahoy there, ahoy, we are castaways
On an island at sea
Just me (me), and me!
Castaways, ahoy, we are castaways

Castaway!!

Step-by-step explanation:

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!
