(1) The graph of a function f is sketched.

(a) Estimate the value of    f(-2) = 3

(b) For what values of x does ?      -3, -1, 1, 2, 3

(c) Estimate the values of  x for which       -2 and -2.8

(2)  Consider the function

(a)

(b)

(c)  What is the domain of f ?   All real numbers
(The only thing that could go wrong is if a negative was plugged into the square root, but that will never happen because x only gets plugged into the radical if x is greater than or equal to 3, hence not negative.)

(3) Find the domain of the function

The domain will be all values x for which
