Answer 3

The table looks like this,
x=1,2,3,5
y=1,1,-3,-3

Answer 4

okay lets do first part
just look at x values if there are x's repeating then relation is not function

Answer 5

So it would be a function because none of the x value's repeat

Answer 6

good !!

Answer 7

for part b they gave u equation
and f(6) which mean h=6 so replace h by 6 and then solve

Answer 8

15h+6
15(6)+6=96?

Answer 9

nice!!!

Answer 10

So I calculated it and then interpreting the meaning.. would I just say f(6)=hours?

Answer 11

y is output
and x is input
