Question

a. F(x) = 3x + 1


b. F(x) = 3 - 2x


c. F(x) =
$\frac{2}{3} x - 5$


​

Answer 1

Resposta:

a)13

b)1

c)-19/9

Explicação passo-a-passo:

a) x= 3+1

x=4

↓

F(4) = (3 × 4) + 1

F(4) = 12+1

↓

R= 13

b) x= 3-2

x= 1

↓

F(1) = 3 - (2 × 1)

F(1) = 3 - 2

↓

R= 1

c) x= 2/3 - 5

x= -13/3

↓

F(-13/3) = 2/3 × (-13/3) - 5

F(-13/3) = 26/9 - 5

↓

R= -19/9
