Tutorial Exercise
From the graph of
f
, state each
x
-value at which
f
is discontinuous. For each
x
-value, determine whether
is continuous from the right, or from the left, or neither.
Part 1 of 7
To find the numbers for which
f
is discontinuous, we look for
x
-values for which the function is not
defined or the left and right limits do not match.
f

2
continuous from the right
continuous from the left
neither
Part 2 of 7
Moving right, the next
x
-value for which
f
(
x
) is discontinuous is
x
= 3-1
.

Part 3 of 7
At
x
= −1, the left and right limits do not match. Also, note that
f
(−1) is on the portion of the graph when
approaching from the left. Therefore, at this point
f
is which of the following.
4
continuous from the right
continuous from the left
neither
Part 4 of 7
Moving further right, the next
x
-value for which
f
(
x
) is discontinuous is
x
= 51
.
Part 5 of 7
At
x
= 1, the left and right limits do not match. Also, note that
f
(1) is on the portion of the graph when
approaching from the right. Therefore, at this point
f
is which of the following.
