Question

Seja a função f definida por f(x) = 4.x – 2, determine o valor de f(5) + f(1 ) *

(a)11
(b)20
(c)22
(d)18
(e)17​

Answer 1

f(5) = 4 . 5 - 2 = 20 - 2 = 18

f(1) = 4 . 1 - 2 = 2

f(5) + f(1) = 18 + 2 = 20. B

Answer 2

Resposta:

f(x) = 4.x – 2

f(5)=4*5-2=18

f(1)=4*1-2 = 2

f(5) + f(1 ) =18+2 = 20
