I really with this Pre Calculus problem =[

In summary, the conversation is about different equations involving x and y, including a square root and absolute value. The speaker suggests plugging in numbers and plotting points to better understand the graph. The notation used is not clear.

sketch and graph
1. y= [x][/3] +2
2. y= squareroot x-3
3. y= Ix-2I
4. y= [y][/2] - 1

If you're not sure what the graph looks like, then just plug in some numbers for x, (x=1, x=2, x=3) and then plot the points. Then just connect them with a smooth line.

I don't actually understand your notation. What are those square brackets and "I"s?

I don't understand even one of these. What do the square brackets mean?

But I'll take a stab at (2) :tongue2:

Yes what are the square brackets?

I think it's pretty straight forward, albeit bizarre notation. The brackets mean nothing, and the "I...I" are supposed to be absolute value bars "|...|".
