  1. Função do 1º grau ou Afim C.E f(x)= a x + b É toda função do tipo: a ≠ 0 a Coeficiente angular b Coeficiente linear RETA Gráfico :

  2. -b a Função do 1º grau ou Afim f(x)= a x + b y b x =0 Coef. linear f(0) = b α x y = 0 tg α = a Coef. angular RAÍZ

  3. -3 2 Crescente Função do 1º grau ou Afim f(x)= 2x + 3 y a > 0 3 x =0 Coef. linear f(0) = 3 y = 0 α x tg α = a = 2 Coef. angular RAÍZ

  4. 3 2 Decrescente Função do 1º grau ou Afim f(x)= - 2x + 3 y Coef. linear a < 0 3 x =0 f(0) = 3 y = 0 α β x α + β = 180 º a = - tg β = - 2 Suplementares RAÍZ Coef. angular - tg β = tg α
