a. Solve for x:  1/4 + (2/3)x = 3/4
b. Solve for b:  2(b + 1) = -2(2b - 4)
c. Solve for n:  2n ≤ -4n - 12
d. Subtract & Simplify:  (x^2 + x - 1) - (2x^2 - x + 5)

e. Briefly describe what a function is.
f. The set of outputs of a function is called what?
g. The set of valid inputs to a function is called what?
h. No or Yes:  -3.14 is in the interval (-3.5, 1.618].
i. No or Yes:  If t = 6.28, then t satisfies:  -10 ≤ t ≤ 6.28

j. Edith is 32 years older than Betty.  Let E represent Edith's age 
   (in years). Write an algbraic expression to represent Betty's age.

k. Let P represent the original price of the CalcUla8or calculator. Write 
   an algebraic expression to represent the CalcUla8or price when it's
   discounted by 25%.

l. Herb sells fake bitcoins for $2 each. In order to break even Herb must
   sell 314 fake bitcoins. How much money will Herb make if he sells 999 
   fake bitcoins?

m. Write the ordered-pair for output  0  and input  -3.14.
n. The ordered-pair (-2, 4)  is graphed (plotted) in what quadrant?
o. The ordered-pair (3, -3) implies an input of ___ maps to an output of ___.
p. If Q(t) = -4 - 2(t), then Q(t) = 24 when t equals what?
q. If H(n) = 3 / (4 - n), then H(4) = _____

The next two problems use function:  f(x) = -5(x)^2 - 5

r. Evaluate:  f(0)
s. Evaluate:  f(-2)

The last two problems use the following set A of ordered-pairs.
A: { (-2, 2) (-1, 1) (0, 0) (1, 1) (2, 2), (-3, 0), (0, -2) }

t. No or Yes:  Set A could be function. Explain your answer.
u. Draw a cartesian coordinate system and plot the points in set A.
