Character Test

1. Given , find C(2) and C(-4).

0 and -24

16 and 40

0 and 40

-24 and 16

2. Graph on your graphing calculator and then give the domain and range.

D: [-2, 2] R: (-infinity, 6)

D: (-infinity, infinity) R: (-infinity, 6]

D: (-infinity, infinity) R: [6, infinity)

D: [0, infinity) R: [6, infinity)

3. Find the slope through the points (4, -2) and (-1, 6).

-5/8

8/5

-8/5

8/3

4. Find the slope of the linear equation:

-1/2

-6

-4

5. Write the equation of the line given slope of 5 and y-intercept of -2.

Y = 5x - 2

Y = -2x + 5

Y = 5x + 2

5x - 2y = 3

6. Write the equation of a line with slope and through the point (9, -3).

Y = 2/3 x - 6

Y = 2/3 x - 9

Y = 2/3 x - 3

Y = 2/3 x - 11

7. Write the equation of the line through the point (-1, 5) and perpendicular to the line 4x + y = 6.

Y = 1/4 x + 6

Y = -4x + 1

Y = 1/4 x + 21/4

Y = 1/4 x + 19/4

8. Personal Savings Using data from 2020 to 2060, the personal savings rate (as a percent of disposable income) of Americans can be modeled by the function . Use the model to estimate the personal savings rate in 2025 to the nearest tenth.

9. Cable Bill A cable company charges a flat monthly fee of $95 for basic channels and an additional $7 for each premium channel. Write an equation to model the cable company's monthly fees.

Y = 7x + 95

Y = 95x + 7

Y = 102x

Y = 7x

10. Blood Alcohol Percent Using the table on pg 72 #49, what does f(4) equal? Tell what this represents in this situation.

F(4) = 0.18; With 4 drinks there is a blood alcohol percent of 0.18.

F(4) = 0.18; When a 100 pound woman has 4 alcoholic beverages, she has a blood alcohol percent of 0.18.

F(4) = 0.18; With 4 alcoholic drinks a person will have a blood alcohol percent of 0.18.

F(4) = 0.20; With 4 alcoholic drinks, a person will have a different blood alcohol percent.
