Calculus

Section 2.5
what you did is correct, but you missing some values of x
dicontinuous:
x=-2 (hole),
x=-1 (infinite discontinuity),
x=0 (hole),
x=1 (point, hole)
sure, just functions are more complex, you will deal with
the limit of a function of two variables:
the continuity of a function of two variables at a point
the limit of a function of three or more variables and verify the continuity of the function at a point
