The is the set of dependent or
y-values of a function.
A. domain
B. range

OPTION B

Step-by-step explanation:

First it is importanty definition, a relation is a function if and only if each input value has one and only one output value.

The input values are the x-values and the output values are the y-values.

Therefore, "y" is the Dependend variable and "x" is the Independent variable.

Knowing the above, you can understand the definition of "Domain" and "Range".

The Domain is defined as the set of all the possible values  of "x" or the Independent variable

The Range is defined as the set of all the possible values  of "y" or the Dependent variable.

Therefore, you can conclude that the correct answer is the given in the Option B.

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!
