So im stuck on this question. i have no idea where to begin, somebody please help?
1.	Draw the graph of the function f (x) = 2 * ⌈x⌉  for the domain  -2 < x ≤ 1

Help?

Start with some axes on graph paper. Your domain is from -2 to 1 so that's where your x axis has to go from. Then you plug each x value down the line into your function and draw where it is.

But remember to make a hole at -2 because although the domain goes to 2, it doesn't equal 2.

anonymous · Answer

ohh okay :)

anonymous · Answer

sorry. -2. argh.

anonymous · Answer

what do i plug in to get the slope? :o

anonymous · Answer

Do you know the slope-intercept form?

anonymous · Answer

noo

anonymous · Answer

y=mx+b

Everything you need is right there in your original equation. (Remember f(x)=y)

anonymous · Answer

m is the slope.

anonymous · Answer

so down 2 over 1?

anonymous · Answer

?

anonymous · Answer

The slope is the number in front of your x.
