Question 137833
Draw a number line.
Mark two points -4 and 10
Put a black dot at each of those two positions on the line.
Connect those two dots with a heavy line segment.
That is the graph of [-4,10]
-----------
[-4,10] is the closed interval notation for all the points
between -4 and 10 along with the two points -4 and 10.
