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 "|...|".
Separate names with a comma.
