2.

Show that the function f(x) = x^{3} + . is even, odd, or neither.

3.

Determine the equation of a line, in slope-intercept form, that passes through the points (9, -2) and (12, 0).

4.

Write the equation of the function g(x) if g(x) = f(x – 2) +4 and f(x) = x^{3} + 2.

5.

Identify the maximum and minimum values of the function y = 3 cos x in the interval [-2π, 2π]. Use your understanding of transformations, not your graphing calculator.
