Answer 1

Oiê, td bom?

$x = -2\\f(-2) = 2.(-2) + 3\\f(-2) = -4 +3\\f(-2) = -1\\\\x = -1\\f(-1) = 2.(-1) +3\\f(-1) = -2 +3\\f(-1) = 1\\\\x = 0\\f(0) = 2.0 +3\\f(0) = 0 +3\\f(0) = 3\\\\x = 1\\f(1) = 2.1 + 3\\f(1) = 2 +3\\f(1) = 5\\\\x=2\\f(2) = 2.2+3\\f(2) = 4+3\\f(2) = 7$

Bom, agora basta ligar os pontos no gráfico :)

Espero ter ajudado... tchau e bons estudos!
