How do you write the rule for a function

with the table
x=0,2,4,5
y=4,6,8,9

?

5 answers

hint:
y=x+__?

4=0+__

6=2+__

8=4+__

9=5+__

So what would it be? I'm so confused

what would you add to 0 to get 4?
what would you add to 2 to get 6?
etc.

y=x+__

in other words, what would you add to x to get y?

4.. so it'd be 4
