2. QUIT WHILE YOU CAN Smoking has long been connected with serious diseases, such as lung cancer, emphysema, and heart disease. Let's estimate that for every cigarette a person smokes, he or she loses anywhere
from 10 to 15 minutes of his or her life. Assuming the worst (15 minutes of life lost for each cigarette), how much
shorter would the life span be of someone who smoked two packs a day for 35 years? (Each pack contains 20
cigarettes.) Answer in years, days, hours, and minutes. (For example, 42 years, 152 days, 7 hours, and 28
minutes.)

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!
