Do not lose this assessment. Do all your math on your own paper. Do not write on this assessment.

Exercises a-g use the following three functions.

   f(x) = 3 + 2(x)       g(x) = 3(x)^2      h(x) = -4(x) - 9

b.  Evaluate:  g(1)                             [show your math]
c.  Evaluate:  h(3)                             [show your math]
d.  Evaluate:  f(0) + g(0) + h(0)               [show your math]
e.  f(x) = 91  when  x  equals what?            [show your math]
f.  h(x) = 91  when  x  equals what?            [show your math]
g.  Is f(x) an increasing, decreasing, or constant function?

h.  Multiply & Simplify:  (5n + 1)(2n + 2)       [show your math]
i.  Subtract & Simplify:  (5x + 1) - (-2x + 7)   [show your math]
j.  Solve for x:  2x(3 + 7) = 36 - 2x            [show your math]

k.  If  x > 0  and  y < 0, then the ordered-pair (x, y) 
    gets plotted in which quandrant? (I or II or III or IV)

l.  No or Yes: The following ordered-pairs can represent a function.
               Briefly explain your answer.
