A function cannot have the same number of ‘x’ repeated in ordered pairs, so therefore the answer would be D, (2,2) because the x wouldn’t repeat.
Step-by-step explanation:





x = 3 or x = -2 we dont use the (-2) because we have a sqrt
So x =3
If you have 10/20, you need to find a common number that goes into them, in this case it can be 5. divide both numbers by 5 and you will get 2/4, now divide that by 2 because 2 goes into 2 and 4, and you get 1/2.
Hope this helps!
