Okay. So you plugged the given values into the specified variable in the given equation, simplified to get the resulting values, and... then what? Where are you stuck?

Please be complete. Thank you! ;)

First step is to understand what a function is. You can actually find the definition for this and other useful information on the main page of this site. The definition we find on this site is that a function is "a set of mathematical operations performed on one or more inputs (variables) that results in an output" The input here are the x values, the domains "-2, 0, 1, 2, 4"
So now we just plug in the numbers and solve.
y= 3.1-2 = 1/3.12 =0.104
