The term paper deadline is …

The term paper deadline is closing in. Time for a few clarifications from questions you've asked.

First, a correction: in problem 2c, delete the sentence "The integral is improper." It is not, my bad.

Then a few minor points and hints:

• In Problem 1, K is an arbitrary constant. The number of zeroes will -- possibly -- depend on K.

• In 1b, note that f is defined only for x nonnegative. That is: if you find zeroes x<0, they shall be disregarded.

• In 1c, still note that f is defined only for x nonnegative.

• In 2b, "expand" means to write out the product as a thrid-degree polynomial

• 2d: no, you are not supposed to calculate the indefinite integral.
