1)Looking around in your own country, discuss two practical applications in which "piecewise

functions" are used either explicitly or implicitly.

2)To the best of your ability, using mathematical notion or in words, Devise any one of the

functions you have spoken of in part (1) above.

3)If you could only learn one approach to solving quadratic equations, discuss which of the

approaches you would choose and why?

4)Do you wholly agree with the statement that "the domain and range of a quadratic equation will

be [-∞, ∞]"? Provide arguments to support your position.
