Given the above graph of a function , what is ?

Possible Answers:

Correct answer:

Explanation:

Examining the graph, we can observe that, as  approaches .

Given the above graph of a function , what is ?

Possible Answers:

Does Not Exist

Correct answer:

Explanation:

Examining the graph, we can observe that, as  approaches  from the left, .

Example Question #61 : Limits

Screen shot 2015 07 01 at 11.23.33 am

Given the above graph of a function , what is ?

Possible Answers:

None of the above

Does Not Exist

Correct answer:

Does Not Exist

Explanation:

Examining the graph, we can observe that  approaches two different limits as  approaches  ( and ) , depending entirely on which side  approaches from. Therefore, a singular limit does not exist. 

Example Question #64 : Limits

Screen shot 2015 07 03 at 12.33.12 pm

Given the above graph of , what is ?

Possible Answers:

Correct answer:

Explanation:

By examining the above graph of , we can observe that as  approaches  from either side, .

Example Question #65 : Limits

Screen shot 2015 07 03 at 12.42.38 pm

Given the above graph of , what is ?

Possible Answers:

Does Not Exist

Correct answer:

Does Not Exist

Explanation:

By examining the above graph of , we can observe that  produces two different values as  approaches  from either side  and  . Thus, a singular limit does not exist for this function.

Example Question #21 : Finding Limits And One Sided Limits

Given the above graph of , what is ?

Possible Answers:

Correct answer:

Explanation:

Examining the graph of , we can see that as  approaches  from either side,  .

Example Question #67 : Limits

Given the above graph of , what is ?

Possible Answers:

Correct answer:

Explanation:

Examining the graph of , we can see that as  approaches  from the left side,  .

Example Question #71 : Limits

Screen shot 2015 07 03 at 4.27.08 pm

Given the above graph of , what is ?

Possible Answers:

Correct answer:

Explanation:

Examining the graph of , we can see that as  approaches  from either side,  .

Example Question #71 : Limits

Screen shot 2015 07 07 at 4.02.20 pm

Given the graph of  above, what is ?

Possible Answers:

Correct answer:

Explanation:

Examining the graph above, we can determine that  as  approaches  from the left.

Example Question #1 : Limits

For the piecewise function:  

, find .

Possible Answers:

Any real number.

Does not exist.

Correct answer:

Explanation:

The limit  indicates that we are trying to find the value of the limit as  approaches to zero from the right side of the graph.  

From right to left approaching , the limit approaches to 1 even though the value at  of the piecewise function does not exist.

The answer is .
