Jika fungsi f(x)=x−1x+1f\left(x\right)=\frac{x-1}{x+1}f(x)=x+1x−1, maka f−1(1x)=....f^{-1}\left(\frac{1}{x}\right)=....f−1(x1)=....
1f(x)\frac{1}{f\left(x\right)}f(x)1
−1f(x)-\frac{1}{f\left(x\right)}−f(x)1
1f(−x)\frac{1}{f\left(-x\right)}f(−x)1
−f(x)-f\left(x\right)−f(x)
f(−x)f\left(-x\right)f(−x)
