Question

I’m so lost and i really need help :’). this is 9th grade algebra

Answer 1

1 and 2 are functions, 3 is not a function.

Explanation:

One x-value can lead to one y-value. If the x-value leads to more than one y-value like #3, then the relation is not a function.

If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
