Resposta :
f(x) = 5x + 2
f(–3) = 5 * (–3) + 2 = –15 + 2 = –13
f(–2) = 5 * (–2) + 2 = –10 + 2 = –8
f(–1) = 5 * (–1) + 2 = –5 + 2 = –3
f(0) = 5 * 0 + 2 = 2
f(1) = 5 * 1 + 2 = 5 + 2 = 7
f(2) = 5 * 2 + 2 = 10 + 2 = 12
f(3) = 5 * 3 + 2 = 15 + 2 = 17
f(4) = 5 * 4 + 2 = 20 + 2 = 22
Conjunto imagem da função, de acordo com o domínio estabelecido: {–13, –8, –3, 2, 7, 12, 17, 22}
