What do you notice? Why did does this happen

The thing you should notice is that when we multiply a number by 10^n

(where n is the number of zeros that the number has) we move the decimal point on the first number n times to the right.

For example, if we have the number:

7.231 and we multiply it by 100 (there are 2 zeros) then the decimal point is moved two times to the right:

7.231*100 = 723.1

This happens because the base of our math is 10 (the decimal system).

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!
