Question

This table represent a function ? ... What is f(-2)?

Answer 1

Yeah, it tells you values from when x and y are both -2, so I don't know why you need us to tell you.

Explanation:

If you meant to ask something else, the way to find an X value is

Y = -0.5555555555555556 X — 0.3333333333333335

Just plug in x, and you'll get Y.

Answer 2

f(-2) is the f(x) when x is -2. From the table, it is 1.
