Step1: Calculate $f(x)=x+4$ values
For $x=-20$: $f(-20)=-20+4=-16$
For $x=-16$: $f(-16)=-16+4=-12$
For $x=-8$: $f(-8)=-8+4=-4$
For $x=0$: $f(0)=0+4=4$
For $x=4$: $f(4)=4+4=8$
Step2: Calculate $f(x)=2-2x$ values
For $x=0$: $f(0)=2-2(0)=2$
For $x=2$: $f(2)=2-2(2)=-2$
For $x=4$: $f(4)=2-2(4)=-6$
For $x=6$: $f(6)=2-2(6)=-10$
For $x=8$: $f(8)=2-2(8)=-14$
Step3: Calculate $f(x)=-2x+3$ values
For $x=-2$: $f(-2)=-2(-2)+3=7$
For $x=-1$: $f(-1)=-2(-1)+3=5$
For $x=0$: $f(0)=-2(0)+3=3$
For $x=1$: $f(1)=-2(1)+3=1$
For $x=3$: $f(3)=-2(3)+3=-3$
Step4: Calculate $f(x)=-2+2x$ values
For $x=-4$: $f(-4)=-2+2(-4)=-10$
For $x=0$: $f(0)=-2+2(0)=-2$
For $x=3$: $f(3)=-2+2(3)=4$
For $x=4$: $f(4)=-2+2(4)=6$
For $x=6$: $f(6)=-2+2(6)=10$
Step5: Calculate $f(x)=6x$ values
For $x=-8$: $f(-8)=6(-8)=-48$
For $x=-6$: $f(-6)=6(-6)=-36$
For $x=-5$: $f(-5)=6(-5)=-30$
For $x=0$: $f(0)=6(0)=0$
For $x=1$: $f(1)=6(1)=6$
Step6: Calculate $f(x)=3x-6$ values
For $x=-5$: $f(-5)=3(-5)-6=-21$
For $x=-4$: $f(-4)=3(-4)-6=-18$
For $x=-3$: $f(-3)=3(-3)-6=-15$
For $x=-2$: $f(-2)=3(-2)-6=-12$
For $x=-1$: $f(-1)=3(-1)-6=-9$
