Question

03. Dada a função f(x) = 2x-1, determine:
a) f(2)
b) f(-1)
c) f(1)
d) f(0)
e) f(1/2)​

Answer 1

Resposta:

A)3

B) -3

C)1

D)-1

E) 0

Explicação passo-a-passo:

F(x) = 2x-1

A) f(2) = 2 . (2) -1 = 4-1 = 3

B) f(-1) = 2.(-1) - 1 = -2 - 1 = -3

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

D) f(0) = 2 . (0) - 1 = 0 - 1 = -1

E) f(1/2) = 2 .(1/2) -1 = 1 - 1 = 0
