Question 78778
The first question looks weird to me.

You asked:  -3 < x and c < 0

You might have meant:  -3 < x and x < 0

To graph this you make a number line and color in the numbers that are
between -3 and 0.  You make an open circle at the two endpoints -3 and 0
to show they are not included in the set you are graphing.  (That is the
set of all numbers that are greater than -3 and less than 0).  So it
might look something like this

<pre>
 -5   -4  -3  -2  -1  0   1   2  
  |---|---O///|///|///O---|---|
</pre>

I used O for a round circle and //// to show it is shaded.

If you had something different, like -3 <= x and x <= 0, then
the round circle would be filled in solid.  But since it is
-3 < x and x < 0  then the endpoints are not shaded so the
circles are left open, unfilled.

There is another interpretation where you meant something more like:
 -3 < x and y < 0
where x and y would be two different variables.  However 'c' is usually used for a constant, and I am guessing you did not mean to graph this with two different variables.


The second one you do just about the same thing.  
It says -4 < x < -1 which means the same as
-4 < x and x < -1 .   (Something totally different is
-4 < x OR x < -1, and that disjuction is the same as the
second condition, x < -1,
because it is true whenever the first condition is true.)

I hope that is enough of explanation for you
