Question

Dada a função f (x)= 2x+2, calcule:

a) F(0)
b)F (-2)
c)F (3)
d)F (-1)

Answer 1

Explicação passo-a-passo:

$a)f(x) = 2x + 2 \\ f(0) = 2.0 + 2 = 2 \\ b)f( - 2) = 2.( - 2) + 2 = - 4 + 2 = - 2 \\ c)f(3) = 2.3 + 2 = 6 + 2 = 8 \\ d)f( - 1) = 2.( - 1) + 2 = - 2 + 2 = 0$

Answer 2

• F(x) = 2x + 2

a) F(0) = 2x + 2

F(0) = 2 × 0 + 2

F(0) = 0 + 2

F(0) = 2

b) F(-2) = 2x + 2

F(-2) = 2 × (-2) + 2

F(-2) = -4 + 2

F(-2) = -2

c) F(3) = 2x + 2

F(3) = 2 × 3 + 2

F(3) = 6 + 2

F(3) = 8

d) F(-1) = 2x + 2

F(-1) = 2 × -1 + 2

F(-1) = -2 + 2

F(-1) = 0
