f(x) is a polynomial. f(-1) = 4. f(1) = -3. f(4) = -6. Then the graph of f(x) must cross the x-axis at least how many times?

Do I need to know the degree of the polynomial?

I'm converting the book into a game, and this part doesn't seem to make sense. Jean Valjean makes his fortune by finding a cheaper way to make the wax used in making jewelry,. He says "The wax was formerly made with resin and lampblack [soot], and cost four livres the pound. I invented a way of making it with gum shellac and turpentine. It does not cost more than thirty sous [less than two livres], and is much better." Turpentine is made from resin, so surely should be just as expensive? And shellac comes from an Asian beetle, so how is that cheaper than soot? Thanks in advance for any light you can shed on the matter.

12. Suppose you exert a horizontal push on a crate that rests on a level floor, and it doesn’t move. How much friction acts compared with your push?

13. As you increase your push, will friction on the crate increase also?

14. Once the crate is sliding, how hard do you push to keep it moving at constant velocity?

15. What is meant by free fall?

16. Why doesn’t a heavy object accelerate more than a light object when both are freely falling?

17. The ratio of circumference/diameter for all circles is pi. What is the ratio of force/mass for freely-falling bodies?

18. What two principal factors affect the force of air resistance on a falling object?

19. What is the acceleration of a falling object that has reached its terminal velocity?

20. If two objects of the same size fall through air at different speeds, which encounters the greater air resistance?

Vera's piggy bank contained $9.35 in quarters, dimes and nickels. There were six more than two times as many nickels as quarters and four less dimes than quarters. How many of each kind of coin was there in the bank?

I will best answer the person who gives me an explanation along with the correct answer. Thank you so much!
