▼

1) f(-2/5) = (-2/5)² + 2(-2/5) + 6 = 4/25 - 4/5 + 6 = 4/25 - 20/25 + 150/25 = 134/25
2) f(-1.3) = 2(-1.3)² + 5(-1.3) - 10 = 2(1.69) - 6.5 - 10 = 3.38 - 6.5 - 10 = -13.12
3) f(5.4) = -6(5.4)² - 9(5.4) + 11 = -6(29.16) - 48.6 + 11 = -174.96 - 48.6 + 11 = -212.56
4) f(3/4) = (4*(3/4) + 8)² + 5 = (3 + 8)² + 5 = 11² + 5 = 121 + 5 = 126
5) f(1/6) = 7(1/6)² + 18(1/6) = 7(1/36) + 3 = 7/36 + 108/36 = 115/36
6) f(2.9) = 8(2.9)(3(2.9) - 1) = 8(2.9)(8.7 - 1) = 8(2.9)(7.7) = 8 * 22.33 = 178.64
7) f(-5/2) = (-5/2 - 6)(-5/2 + 1) = (-17/2)(-3/2) = 51/4
8) f(-0.5) = 9(-0.5)² + 7(-0.5) = 9(0.25) - 3.5 = 2.25 - 3.5 = -1.25
9) f(-7/3) = -5(-7/3)² + 12(-7/3) + 21 = -5(49/9) - 28 + 21 = -245/9 - 7 = -245/9 - 63/9 = -308/9
10) f(3.2) = 10(3.2 + 2)² - 2 = 10(5.2)² - 2 = 10(27.04) - 2 = 270.4 - 2 = 268.4
