A survey of 70 people found that 40 had the same Internet service provider. The survey reported this information as the ratio 40:70. Four
newspaper articles made this report using different but equivalent ratios.
Which ratio is NOT equivalent to 40:70?
A. 4:7 B. 8:14 C. 20:35 D. 28:45

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!
