graphing a piecewise vertical line

[WeirdClayJisKOOL]

ok so i got really bored in pre-calc, so i decided to create piecewise equations to display my "logo". i got it all done, but it's got about 4 vertical line segments. is there any way to do thoes with piecewise equations? (i've been using the when() function)

also, i currently have each segment as a seperate y= equation. i know that there is a way to have it all in one y=, but there were so many segments i got confused. i'll put what i have and if anyone could combine them for me, that would be great. thanks!

this is what i have:

y1=when(-11<x and x<0,x+7,1/0)
y2=when(-6<x and x<0,x+4,1/0)
y3=when(-11<x and x<1,-4,1/0)
y4=when(-6<x and x<1,-2,1/0)
y5=when(0<x and x<4,-x+7,1/0)
y6=when(0<x and x<2.5,-x+4,1/0)
y7=when(2.5<x and x<4,x-1,1/0)
y8=when(-1<x and x<1,-x,1/0)
y9=when(3.5<x and x<5,x-3,1/0)
y10=when(5<x and x<11,-x+7,1/0)
y11=when(3.5<x and x<5,-x+4,1/0)
y12=when(4<x and x<5,x-6,1/0)
y13=when(2<x and x<4,-2,1/0)
y14=when(2<x and x<5,-4,1/0)
y15=when(5<x and x<6.5,x-9,1/0)
y16=when(6.5<x and x<8,-x+4,1/0)
y17=when(8<x and x<11,-4,1/0)


so basically i want to combine those, and add 4 more for these vertical lines:
x=-1 [1>y>-1]
x=1 [1>y>-1]
x=1 [-2>y>-4]
x=2 [-2>y>-4]



thanks a bunch!!!

You could make it a y= line, just having it be such a huge slope that it looks vertical on the calculator.

yea thats what one of my classmates said. i'll just do that. what about combining the when statements...is it possible?

EDIT:i tried it, and it made a vertical line, but i can't figure out how to get it to only be a certain length...

Just make the range super small.

For a vertical line at x=2, for example, you could use 1.9<x<2.1

ugh. thats one of the faults with these calculators is they have to be y=

One easy solution is to use a data plot (x values in L1, Y values in L2, connected by lines) which also supports vertical lines.
