Question

Can you please help me here? How can youy can graph this?
y=[x]
Waht doea that bracket means?

What does that bracket means?

Answer 1

The answers posted so far are not quite correct.
[x] is also called floor(x).
It denotes the greatest integer less than or equal to x.
So if x is positive just drop the decimal part of x,
e.g. [3.14] = 3.
But if x is negative you must drop the decimal
part of x and subtract 1.
e.g., [-3.14] = -4
The graph does look like a bunch of stairsteps
with a jump at each integer.

Answer 2

The brackets mean integer. That means that whatever value "x" is, "y" is the number rounded down to the nearest ones place.

For example, if x = 3.8, y would equal 3.

If x = 5.0, y = 5

If x = 5.9, y = 5.

The graph would look like stair steps without the vertical lines.

Answer 3

This is the Greatest Integer function. Y is the greatest integer less than or equal to x. So if x = 1.7, y = 1; if x = 2.6, y = 2, etc. The graph should look like a discontinuous stairstep.

Answer 4

those r not brackets. it is like this
y=lxl
those r absolute valuses meanin u must convert the x-value to positive.
eg. x= -2, so make it positive the y=2(if postive ans, it remains postive)
it gives a v shaped graph,
