So I have three tables and I have to tell which are either linear, quadratic, or exponential, then explain why. If someone could do this (i know I sound lazy and I could probably do this myself, but I'm too busy and this really needs to get done.)

The first table.

The x values are: -2,-1,0,1,2.

The y values are: 8,5,4,5,8

The second table.

The x values are: -2,-1,0-1-2

The y values are: -16,-3,0,-1,0

The third table.

The x values are: -2,-1,0,1,2

The y values are:1,.3,.09,.027,.0081
