Question

me ajudem pfv!!!!!!!!!!!!!!!!!!!!!!!!​

Answer 1

Resposta:

Explicação passo-a-passo:

1) 2, 3 e 4

2)

x = -3 => f(-3) = -3 + 2 = -1

x = -1 => f(-1) = -1 + 2 = 1

x = 0 => f(0) = 0 + 2 = 2

x = 2 => f(2) = 2 + 2 = 4

Im(f) = {-1, 1, 2, 4}

3)

x = -3 => f(-3) = 5.(-3) + 2 = -15 + 2 = -13

x = -2 => f(-2) = 5.(-2) + 2 = -10 + 2 = -8

x = -1 => f(-1) = 5.(-1) + 2 = -5 + 2 = -3

x = 0 => f(0) = 5.0 + 2 = 0 + 2 = 2

x = 1 => f(1) = 5.1 + 2 = 5 + 2 = 7

x = 2 => f(2) = 5.2 + 2 = 10 + 2 = 12

x = 3 => f(3) = 5.3 + 2 = 15 + 2 = 17

x = 4 => f(40 = 5.4 + 2 = 20 + 2 = 22

Im(f) = {-3, 2, 7, 12, 17, 22}
