1) Find a function f such that it is both even and odd.

5) The information in the chart gives the salary of a person for the stated years. Model the data with a linear function using the points (1, 24800) and (3, 26600).

Year, x	1990, 0	1991, 1	1992, 2	1993, 3	1994, 4
Salary, y	$23,500	$24,800	$25,200	$26,600	$27,200

16) A function f(x), a point c, the limit of f(x) as x approaches c, and a positive number are given. Find a number > 0 such that for all x, 0 < |x - c| < |f(x) - L| < .

f(x) = -2x - 6, L = -12, c = 3, and = 0.01

18) The slope of the line tangent to the graph of y = lnx² at x = e²

19) If F(x) = x sin x, then find F ' (3pi/2)

20) If H(x) = x³ - x² + 1/x, which of the following is H ''(2)?
