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

Explicação passo-a-passo:

f(x) = 2x - 1

a) f(2)= 2.2-1

f(2)= 4-1

f(2)= 3

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

f(-1)= -2-1

f(-1)= -3

c)f(1)= 2.1-1

f(1)= 2-1

f(1)= 1

d) f(0)= 2.0-1

f(0)= 0-1

f(0)= -1

e) f(1/2)= 2.1/2 -1

f(1/2)= 2/2-1

f(1/2)= 1-1

f(1/2)=0
