Question

Is this set of ordered pairs a function or not a function?
{(3, 2) (3,5) (4, 6) (7, 8)}

Answer 1

Answer:

Not a function

Step-by-step explanation:

The reason the ordered pairs are not a function is because there is no real equation that can get the correct x and y for each. Along with 3 being a x-value twice, which is also a key sign that it's not a function.
