 Test 7
 Time: 1 hour

 A ball that is thrown upward follows the path
, where h(t) represents the height of the
ball above the ground at time t, and t represents the time since
the ball was thrown. How high above the ground did the ball reach?
Answer: The maximum height that the ball reached was 17 units.
 Find a degree polynomial with real coefficients that
has zeros 0, 3i, and 2i.
Answer: .
 Divide .
Answer:

 a)
 List the set of possible rational zeros for
Answer: .
 b)
 Factor completely.
Answer: (x2i)(x+2i)(x1)(x4).

 a)
 Find the equations of all vertical, horizontal, or slant
asymptotes of the graph of
Answer: The equations of the vertical asymptotes are x=1, and
x=1. There are no horizontal asymptotes. The equation of the
slant asymptote is y=3x.
 b)
 Explain how you used the graph of f(x) to verify your findings.
Answer: By looking at the graph of f(x), the values of f(1),
and f(1) are undefined. The graph gets closer and closer to the
lines x=1, and x=1 but it never crosses it.
