Of the provided graphs, the second would be the correct answer.
Functions occur when the input only has one possible output (though the output can be recieved through multiple inputs)
Yellow and 1: Fraction = 1/15 Decimal = .067 Percent = 6.7%
Red and odd: Fraction = 2/15 Decimal = .133 Percent = 1.3%
PS. I rounded decimals to nearest thousandth, and decimals to nearest tenth.
3/16= 0.1875
Though if you mean 16/3 it is 5.333.....
