Question 923782: These questions just have me stumped any help on any of these would be very much appreciated.
In Problems 43– 54, graph the indicated set and write as a single interval, if possible. *ODD ONLY
43. ( 5, 5) U [ 4, 7 ]
45. [ 1, 4) n ( 2, 6 ]
47. (-infinity , 1) U ( 2,infinity )
49. (-infinity , 1) U [ 3, 7)
51.[ 2, 3 ] U ( 1, 5)
53. (-infinity , 4) U ( 1, 6 ]
Thanks in advance I appreciate it. Anything will help

You can put this solution on YOUR website! For each problem:
Step 1: Draw a number line.
Step 2:  stands for union,  stands for intersection. So find the union or intersection of each set of intervals before sketching.
Step 2: Sketch each interval. Remember [a,b] is the closed interval from a to b, (a,b) is the open interval from a to b (can be drawn using hollow circles at a and b to symbolize that a,b are not in the interval), and [a,b) means the interval includes a but not b.
For example, ) would just be the interval (1,5), so you would sketch (1,5), making sure you do not include 1 or 5.
