2.)This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part.
From the graph of f, state each x-value at which f is discontinuous. For each x-value, determine whether f is continuous from the right, or from the left, or neither.
Step 1
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.
Starting from the left and moving right, the first x-value for which f(x) is discontinuous is x = .
At this point, f(x) is not defined. Therefore, at this point f is which of the following.
continuous from the right
continuous from the left
neither
Explanation / Answer
From the graph we can say
The function isdiscontinuous at x=-1 from left to right
The function left hand limit and right hand limit does not match at x=-1
Similarly at x=1, x=2 the function is discontinuous
At the point x =2 function is not defined and neither continuous
