Q

FUNÇÃO

- quando não é uma função ?

A
  • quando sai duas flechas do msm lugar e quando sobra no domínio ( pode sobrar apenas no contra domínio)
17
Q

FUNÇÃO

- quem é a função ?

A
  • O Y

- F(X)= Y

18
Q

FUNÇÃO

  • função par ?
  • função ímpar ?
A
  • A função par , tem os domínios diferentes e imagens ( resultado) iguais. F(2)= 2^2 + 1 = 5 F(-2) = (-2)+ 1= 5
  • função ímpar, tem os domínios e imagens opostas. F (2)= 2^3+2 =10 F(-2) = (-2)^3+ (-2)= -10
