2. Which set of ordered pairs represents y as a function of x? F. ((0,1) (0,-8) (1,-2) (0,7)} G. {(2,-4) (3, -6) (1, 0) (5, -7)} H. {(9,8) (9.0) (-9,6) (10, 12)} J. {(-3,9) (2, 5) (-3,7) (2, 0)}​

Step-by-step explanation:

yes, it is a function. why ?

because every used x value has one unique y value assigned. that is the definition of a function. if any x value could lead to 2 or more different results (y values), it is not a function.

the domain is the interval/set of valid x (input) values to the function.

the range is the interval/set of produced and valid y (functional result) values.

so, the domain is the set of all the x values of the ordered pairs

{-7, 1, 4, 5, 8}

the range is the set of y values corresponding to the used x values

{-9, -7, -2, 3, 8}
