Answer 1

Resposta:

1)

para cima: a, c, d

para baixo: b, e, f

Explicação passo-a-passo:

2)

f(-1) = 1.(-1)² - 4. (-1) + 3 = 1.1 + 4 + 3 = 8 (-1, 8)

f(0) = 1.(0)² - 4.0 + 3 = 1.0 + 0 + 3 = 3 (0, 3)

f(1) = 1.(1)² - 4.1 + 3 = 1.1 - 4 + 3 = 0 (1, 0)

f(2) = 1.(2)² - 4.2 + 3 = 1.4 - 8 + 3 = -1 (2, -1)

f(3) = 1.(3)² - 4.3 + 3 = 1.9 - 12 + 3 = 0 (3, 0)

f(4) = 1.(4)² - 4.4 + 3 = 1.16 - 16 + 3 = 3 (4, 3)

f(5) = 1.(5)² - 4.5 + 3 = 1.25 - 20 + 3 = 8 (5, 8)

3)

f(-1) = -1.(-1)² + 4. (-1) + 0 = -1.1 - 4 + 0 = -5 (-1, -5)

f(0) = -1.(0)² + 4.0 + 0 = -1.0 + 0 + 0 = 0 (0, 0)

f(1) = -1.(1)² + 4.1 + 0 = -1.1 + 4 + 0 = 3 (1, 3)

f(2) = -1.(2)² + 4.2 + 0 = -1.4 + 8 + 0 = 4 (2, 4)

f(3) = -1.(3)² + 4.3 + 0 = -1.9 + 12 + 0 = 3 (3, 3)

f(4) = -1.(4)² + 4.4 + 0 = -1.16 + 16 + 0 = 0 (4, 0)

f(5) = -1.(5)² + 4.5 + 0 = -1.25 + 20 + 0 = -5 (5, -5)

4)

f(-1) = -1.(-1)² + 2. (-1) - 1 = -1.1 - 2 - 1 = -4 (-1, -4)

f(0) = -1.(0)² + 2.0 - 1 = -1.0 + 0 - 1 = -1 (0, -1)

f(1) = -1.(1)² + 2.1 - 1 = -1.1 + 2 - 1 = 0 (1, 0)

f(2) = -1.(2)² + 2.2 - 1 = -1.4 + 4 - 1 = -1 (2, -1)

f(3) = -1.(3)² + 2.3 - 1 = -1.9 + 6 - 1 = -4 (3, -4)

f(4) = -1.(4)² + 2.4 - 1 = -1.16 + 8 - 1 = -9 (4, -9)

f(5) = -1.(5)² + 2.5 - 1 = -1.25 + 10 - 1 = -16 (5, -16)
