  1. Plug x=2x = -2: Plug x=2x = -2 into the equation to find yy.\newliney=2(2)2y = 2(2)^{-2}\newliney=2(14)y = 2(\frac{1}{4})\newliney=2×0.25y = 2 \times 0.25\newliney=0.5y = 0.5
  2. Plug x=1x = -1: Plug x=1x = -1 into the equation to find yy.\newliney=2(2)1y = 2(2)^{-1}\newliney=2(12)y = 2(\frac{1}{2})\newliney=2×0.5y = 2 \times 0.5\newliney=1y = 1
  3. Plug x=0x = 0: Plug x=0x = 0 into the equation to find yy.\newliney=2(2)0y = 2(2)^0\newliney=2(1)y = 2(1)\newliney=2y = 2
  4. Plug x=1x = 1: Plug x=1x = 1 into the equation to find yy.\newliney=2(2)1y = 2(2)^1\newliney=2(2)y = 2(2)\newliney=4y = 4
  5. Plug x=2x = 2: Plug x=2x = 2 into the equation to find yy.\newliney=2(2)2y = 2(2)^2\newliney=2(4)y = 2(4)\newliney=8y = 8
  6. Plug x=3x = 3: Plug x=3x = 3 into the equation to find yy.\newliney=2(2)3y = 2(2)^3\newliney=2(8)y = 2(8)\newliney=16y = 16
