just. determine if function or not

Ok so basically if an input (x) has more than one output (y) it is NOT a function. One output having more than one input is okay though.

So G) is a function, bc for every x there is just 1 y

H) is not a function

I) is not a function either

Then the 6 below ( i can't read their numbers so they're just gonna be 1-6, top 3 from left to right then the bottom three from left to right)

1. function

2. not a function

3. function

4. function

5. not a function

6. not a function

i might be wrong, but i hope this helps!

G-Function, H-Not a function, I-Not a Function

Step-by-step explanation:
