Compute the limits and determine the function value. Write "DNE" if the limit does not exist or
the value is undefined.
lim
f(x) =
-2
x →3-
lim
f(2) =
x →3+
f(3) =
-2
Since the above three quantities are all defined and equal
we know that f is
continuous
O at x
= 3.
Is f continuous everywhere? If not, list all x-values for which f is discontinuous. Separate
multiple answers with a comma.
