Ex.1 a) F(-2) , F(2), F(-3)+F(3)

=>

F(-2) = -6x + 3 = -6 × (-2) + 3 = 12+3 = 15

F(-2) = 15

F(2) = -6x + 3 = -6 × 2 + 3 = -12 + 3 = -9

F(2) = -9

F(-3) = -6x + 3 = -6 × (-3) + 3 = 18 + 3 = 21

F(-3) = 21

F(3) = -6x + 3 = -6 × 3 + 3 = -18 + 3 = -16

F(-3)+F(3) = 21 + (-16) = 5

Raspuns:

F(-2) = 15

F(2) = -9
