7) Does the table show a function? *

Answer:
yes
Step-by-step explanation:
Function rule: one input (x) can't have more than 1 output
-but, one output (y) can have more than one input
let's check:
3 and 5
1 and 1 ( this is still a function because it hasn't violated the "ne input (x) can't have more than 1 output" rule
-2 and -5
-3 and -7
so yes
