What’s figure 0 ? and the growth and the rule ?

Hi, this is Santa's elf speaking. My name is Tiny and Santa told me to talk to you. He's noticed that you've been naughty lately. He says if you do one more naughty thing, you're gonna end up on the naughty list this year. The only way to not end up on the naughty list is to put this message on 10 comment sections. Do it and you've got the Christmas spirit!

y = x + 95

y = 42 + 95

y=137 mm hg

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!
