Question

Calcule o valor da função f(x) = 2x-1/2, para x=1 *

Answer 1

Oie, Td Bom?!

f(x) = 2x - 1/2

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

f(1) = 2 - 1/2

f(1) = [4 - 1]/2

f(1) = 3/2

Answer 2

Explicação passo-a-passo:

$\sf f(x)=2x-\dfrac{1}{2}$

=> Para $\sf x=1$

$\sf f(1)=2\cdot1-\dfrac{1}{2}$

$\sf f(1)=2-\dfrac{1}{2}~~~~~~~~~mmc(1,2)=2$

$\sf f(1)=\dfrac{2\cdot2-1}{2}$

$\sf f(1)=\dfrac{4-1}{2}$

$\sf \red{f(1)=\dfrac{3}{2}}$
