Soluções para a tarefa
Resposta:
Explicação:
D = {-2, -1, 0, 1, 2}
f(x) = 3x g(x) = -x h(x) = -x + 1
f(-2) = 3 * (-2) = -6 g(-2) = -(-2) = 2 h(-2) = -x + 1 = -(-2) + 1 = 3
f(-1) = 3 * (-1) = -3 g(-1) = -(-1) = 1 h(-1) = -x + 1 = -(-1) + 1 = 2
f(0) = 3 * 0 = 0 g(0) = -0 = 0 h(0) = -x + 1 = -0 + 1 = 1
