Di ketahui F(2-x) =x+1/1-2x Tentukan fungsi F(x)

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

misal :
2 - x = a
x = 2 - a

soal menjadi
f(a) = (2 - a + 1) / (1 - 2(2 - a)
f(a) = (3 - a) / (1 - 4 + 2a)

f(x) = (3 - x) / (2x - 3)

semoga berguna +_+

[tex]\displaystyle f(2-x)=\frac{x+1}{1-2x}\\f(2-x)=\frac{x-2+3}{4-2x-3}\\f(2-x)=\frac{-(2-x)+3}{2(2-x)-3}\\\boxed{\boxed{f(x)=\frac{3-x}{2x-3}}}[/tex]
