Question

Data a função F (×)=3×-2 determine: F (-2) , f (-1), f (0) ,
f (2)

Answer 1

F (X) = 3x - 2

F(-2) = 3 . (-2) - 2 = 
F(-2) = -6 - 2 = - 8

F( -1) = 3. (-1) - 2=
F(-1) = -3 - 2 = -5

F(0) = 3.0 - 2
F(0) = 0 - 2= -2

Answer 2

F(-2) = 3•(-2) - 2 = -6 - 2 = -8
F(-1) = 3•(-1) - 2 = -3 -2 = -5
F(0) = 3•(0) - 2 = -2
F(2) = 3•(2) - 2 = 6 - 2 = 4
