Question

dada a função f(x)=2x-1, determine. f(2), f(1)
f(-1)
f(0)
f(1/2)

Answer 1

Resposta:

f(x)=2x-1

f(1) = 2.1 - 1

f(1) = 2 - 1

f(1) = 1

==============

f(x)=2x-1

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

f(-1) =  -2 - 1

f(-1) = -3

=============

f(x)=2x-1

f(0) = 2.0 - 1

f(0) = 0 -1

f(0) = -1

=============

f(x)=2x-1

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

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

f(1/2) = 1 - 1

f(1/2) = 0

===============
