1) Suppose that a function f(x) is defined for all real values of x, except x = xo. Can anything be said about lim x → x 0 f ( x ) ?

Give reasons for your answer.
2) If x4f(x) ≤ x2 for x in [-1,1] and x2f(x) ≤ x4 for x < -1 and x > 1, at what points c do you automatically know lim x → c f ( x ) ? What can you say about the value of the limits at these points (x = +/-1) and at x = 0?

3) Explain why the following statement is true or false:
If g is continuous and increasing on its entire domain, then g(x2) > g(x1) when x1 < x2
