Questions are in the links above.



I completed 4 out of the 8 problems. I just don't know how to do these (As in I know what I'm doing is wrong).

What don't you understand about problem 1? Establish continuity between the two parts by selecting k Hint: The value of f(3) must be the same when approaching x = 3 from the right and the left.

2. A plot is required.

3. After making the plot for 2, evaluate the limits.

4. Evaluate the limit.

IMO, these are very simple problems.

4 would be 0 correct?

Hello Jonny B. Welcome to PF !

According to the rules of this Forum, you need to show what you've tried before we can help you.

Also, you should include no more than two problems per thread.

The answer to #4 is zero.Added in Edit:
I do notice now that #2, and #3 are closely related.
