Chapter 8 Test Review
1. An arrow is shot into the air with
an upward velocity of 64 feet per
second from a hill 32 feet high.
The height h of the arrow (in
feet) can be found by using the
model ℎ = −16 2 + 64 + 32
where t is the time (in seconds).
When will the arrow be 64 feet
above the ground? Round your
answer to the nearest
hundredth. (Yes this was on your
review from Monday, and YES
almost everyone got it wrong. I
put step-by-step instructions on
the answer page)
Find the domain, range, maximum
or minimum and the solution(s)
(solutions is the same as zero and
roots) of each graph below.
2.
3.
Use the equation y = -(x – 2)2 + 4.
4. Is the graph opening up or
down?
5. Does it shrink or stretch?
6. What is the vertex?
7. What is the maximum or
minimum?
8. Solve by factoring.
6x2 - 10 = -11x
9. Solve.
-3(x – 6)2 + 19 = 7
10.
Solve by completing the
square.
3x2 – 6x = 9
11.
How many solutions does
the equation have?
2x = 3 + 2x2
12.
Solve using the quadratic
formula.
12x = -9x2 – 4
13.
Solve.
Y = x2 – 4
Y = 5x – 10
14.
Write the equation in
vertex form.
x2 – 2x = 48
