Can you describe what the graph of interval [-4.10] looks like?

Answer by  UpwardBoundPrecalcTutor (128)

Do you really mean the interval[-4,10]. Its graph would be a numberline with a filled in circle at -4, a filled in circle at 10 and shading in for all points betweeen. If you really mean [-4. 10] that is no interval but just the point -4. 10 on the number line, 1/10 of the distance from -4 to -5.

An interval is just a range of numbers. [-4,10] means all numbers between -4 and 10, inclusively. So, to graph this interval, you need to draw a number line that extends a little beyond -4 and a little beyond 10. Be sure to mark -4 and 10 on the number line with brackets, then shade between the numbers.
