Question

Please help! Will award medal!

The problem says to find the limit as x--> -1 , but at -1 there is a hole in the graph. What does this mean about the limit? Please help, I need walked through this.

Answer 1

Example please. do you have a picture of the graph?

Answer 2

he open circle indicates that that point is *NOT* on the graph, but all points leading up to it are
so for example if it's at x=2 and the circle is at (2,5) then the point (2,5) is *NOT* part of the graph
however (1.9, f(1.9)) and (1.99, f(1.99)) may be

the closed (filled in) circle means that point *IS* included, but no points beyond it
so if a line starts at (2,3) and goes off to the right from there then absolutely no points left of (2,3) are to be included as a point of that line

hard to explain without pictures I hope this helps

Answer 3
