Given f(x)= 4x^3-36x-4x^2+36/2-3x+x^2 Is it possible for f(x) to have a removable AND and infinite discontinuity at the same point (value of a). Offer support to your answer as to why...

fin the limit of (1-cos2x-cos4x)/x as x->0 and show all work!

How are the numbers selected when using a table of values to find the limit of a problem like: lim x->2 x^3-8/x-2

limx+1/x^2-x-2 x-->2 table x 1.9 1.99 1.999 2...

no graph provided lim x=? x->9

I cant copy an paste the graph but it looks like this is a straight line with an open circle like this "0" and its location is (-1,-2) the line continues going up to the right...
