instructions for submitting your quiz in the Unit Quizzes Module.

4.) Finally, be sure to sign the honor statement. Without this your quiz may be invalidated.

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.

Determine if the function is even, odd, or neither.

5x

1) y =

x2 - 9

A) Even

B) Odd

C) Neither

Find f(x) and g(x) such that h(x) = (f g)(x).

5

2) h(x) =

6x + 3

A) f(x) =

6x + 3, g(x) = 5

C) f(x) =

, g(x) = 6x + 3

x

Find the domain and range.

14

3) f(x) =

14 - x

A) Domain: (- , 14) (14, ); Range: (- , )

C) Domain: (- , ); Range: (- , )

Solve the problem.

4) A power plant is located on a river that is 650 feet wide. To lay a new cable from the plant to a location in a city

2 miles downstream on the opposite side costs \$200 per foot across the river and \$150 per foot along the land.

Suppose that the cable goes from the plant to a point Q on the opposite side that is x feet from the point P

directly opposite the plant. Write a function C(x) that gives the cost of laying the cable in terms of the distance x.

2 mi

650 ft

A) C(x) = 200 x2 + 6502 + 150(2 - x)

C) C(x) = 200 x2 + 6502 + 150(10,560 - x)

B) C(x) = 200(650 - x) + 150(2 - x)

D) C(x) = 150 x2 + 6502 + 200(10,560 - x)

5) If f(x) = 9x - 5 and g(x) = 3x2 + 2x - 6, find g(f(-3)).

A) 3002

B) -194

C) -166

D) 130

6) 4y + 2x = 4

For the function f, construct and simplify the difference quotient

7) f(x) =

f(x + h) - f(x)

.

h

1

2x

Solve the problem.

8) If f(x) = 4x2 + 2x + 7 and g(x) = 2x - 4, find g(f(x)).

9) A deep sea diving bell is being lowered at a constant rate. After 10 minutes, the bell is at a depth of 300 feet.

After 50 minutes the bell is at a depth of 1400 feet. What is the average rate of lowering per minute? Round your
