| y | (-2 - 1)(-2 + 5) = -3 * 3 = -9 | (-1.5 - 1)(-1.5 + 5) = -2.5 * 3.5 = -8.75 | (-1 - 1)(-1 + 5) = -2 * 4 = -8 | (-0.5 - 1)(-0.5 + 5) = -1.5 * 4.5 = -6.75 | (0 - 1)(0 + 5) = -1 * 5 = -5 | (0.5 - 1)(0.5 + 5) = -0.5 * 5.5 = -2.75 | (1 - 1)(1 + 5) = 0 * 6 = 0 | (1.5 - 1)(1.5 + 5) = 0.5 * 6.5 = 3.25 | (2 - 1)(2 + 5) = 1 * 7 = 7 |
