Which of the following set of ordered pairs is a function?

C

Step-by-step explanation:

because it doesn't have an x number written twice like for example

(2,0) (2,8) (3,0)

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

combine all like terms then its just a 2 step equation
