Please help! I am so confused in my college algebra class and my professor goes way too fast! Looking for a friend! Thank you!!!

Recall that f(x) = (x - 3) has a zero at x = 3. So if you were given a zero as x = 5, then one of the factors of the polynomial would be (x - 5). Our problem gives you the zeros. Use those zeros...

How would you describe the difference between direct variation and joint variation in words? Use examples to help illustrate.

Most formulas are actually examples of variation. Pick a well-known formula and describe the type of variation as well as the constant of variation, k. Example: The area A of a triangle with base...
