Use the scenario to answer the question.

the formula for volume of a prism is v=bh, where v represents the volume, b represents the area of the base, and h represents the height of the prism.

arletha has the measurement of 23 in3 but does not know which variable this measure represents in the formula. which value could arletha's measurement represent?

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!
