  (x, y) = (-2, 0), (-1, 3), (0, 4), (1, 3), (2, 0)

Step-by-step explanation:

Put the value where x is in the formula and do the arithmetic. As you know, a power of 2 means the value is multiplied by itself. You do that first, then subtract from 4. For repetitive calculations a calculator or spreadsheet can be helpful.

For example, ...

  for x=-2, you have y = 4 -(-2)^2 = 4 -4 = 0

Here are the others:

  (x, y) = (-2, 0), (-1, 3), (0, 4), (1, 3), (2, 0)
