  1. Check f(x)=1f(x)=-1: Plug in x=0x=0 into each function to see if f(x)f(x) equals 1-1.\newlineA. f(0)=3(0)=0f(0)=3(0)=0, not 1-1.
  2. Verify x=2x=2: Now check x=2x=2 in the functions that worked for x=0x=0.
    B. f(2)=(22)1=11=0f(2)=\left(\frac{2}{2}\right)-1=1-1=0, this one works for x=2x=2.
  3. Verify x=6x=6: Finally, check x=6x=6 in the remaining function B.\newlineB. f(6)=621=31=2f(6)=\frac{6}{2}-1=3-1=2, this one works for x=6x=6.
