Question

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

Answer 1

Oie, Td Bom?!

f(x) = 2x - 1/2

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

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

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

f(1/2) = 1/2

Answer 2

Explicação passo-a-passo:

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

=> Para $\sf x=\dfrac{1}{2}$:

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

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

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

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