Question

dada a função f(x) = 2x - 1, determine:
a)f(2)
b)f(-1)
c)f(1)
d)f(0)
????

Answer 1

Resposta:

Explicação passo-a-passo:

-1

X= 2x -1

X-2x= -1

X= -1

Answer 2

Resposta:

a) f(2)

$f(x)=2x-1\\\\f(2)=2*2-1\\\\f(2)=4-1\\\\f(2)=3$

b)f(-1)

$f(x)=2x-1\\\\f(-1)=2*-1-1\\\\f(-1)=-2-1\\\\f(-1)=-3$

c)f(1)

$f(x)=2x-1\\\\f(1)=2*1-1\\\\f(1)=2-1\\\\f(1)=1$

d)f(0)

$f(x)=2x-1\\\\f(0)=2*0-1\\\\f(0)=0-1\\\\f(0)=-1$
