Graph f(x)=lx-3l and x=3 on the same set of coordinate axes. Write a description of the relationship between the two graphs.

Question

i graphed absolute value of x-3
but how do you graph x=3

Answer 1

Since you have no y, you'll use the point (-3,0) and then draw a straight vertical line through this point. Anytime you have x = something, it will result in a vertical line through that point on the x-axis. Whenever you have y = something, it will result in a horizontal line through that point on the y-axis. For some reason, calculators appear to not accept x=, so you just have to do it by hand.

Answer 2

Oh wait, I meant graph (3,0) and draw a verticle line. Whoops!
