Question

Dada a função (polinomial 1 grau ) o F(X)= 2x-4 Determine:

F(1)=

F(2)=

F(3)=

F(-1)=

F(0)=

F(-3)=

Answer 1

F(x) = 2x - 4
F(1) = 2. (1) - 4
F(1) = 2 - 4
F(1) = -2

F(x) = 2x - 4
F(2) = 2. (2) - 4
F(2) = 4 - 4
F(2) = 0

F(x) = 2x - 4
F(3) = 2. (3) - 4
F(3) = 6 - 4
F(3) = 2

F(x) = 2x - 4
F(-1) = 2. (-1) - 4
F(-1) = -2 - 4
F(-1) = -6

F(x) = 2x - 4
F(0) = 2. (0) - 4
F(0) = 0 - 4
F(0) = -4

F(x) = 2x - 4
F(-3) = 2. (-3) - 4
F(-3) = -6 - 4
F(-3) = -10

Answer 2

F(1)=  2.1-4= -2
F(2)=  2.2-4= 0
F(3)=  2.3-4= 2
F(-1)= 2.(-1)-4= -6
F(0)=  2.0-4= -4
F(-3)= 2.(-3)-4= -10
