Final Exam

• 42 content-related questions and 3 open-ended self-reflection responses

• Parallel/Perpendicular Lines (6)

• Linear Functions (15)

• Systems of Equations and Inequalities (11)

• Piecewise-Defined Functions (10)

• Self-reflection (3)

Let's get into our review questions!

There are only 7.

Multiple Choice

1. Parallel/Perpendicular Lines

Write an equation of a line that is parallel to

 $y=4x-6$  and has a y-intercept of 10.

•  $y=4x-6$  

•  $y=4x-10$  

•  $y=4x+10$  

•  $y=10x$  

Multiple Choice

2. Linear Functions

Is this a function?

• Yes, each input is assigned to exactly one output.

• No, there is at least one input that is assigned to more than one output.

Multiple Choice

3. Linear Functions

Let  $f\left(x\right)=\left(\frac{1}{2}\right)x-1$  .

Calculate  $f\left(8\right)$  .

• 8

• 5

• 4

• 3

Multiple Choice

4. Systems of Linear Equations and Inequalities


True or False: (0, 1) is a solution to the system of equations.

• True, the point makes boht equations true.

• False, the point does not make both equations true.

Multiple Choice

5. Systems of Linear Equations and Inequalities

True or False: (0, 0) is a solution to the inequality.

• True

• False

Multiple Choice

6. Piecewise-Defined Functions

Identify the domain and range of the absolute value function.

• Domain: All real numbers          Range:  $y\ge0$  

• Domain:  $x\ge0$  Range:  $y\ge0$  

• Domain: All real numbers.     Range: All real numbers

Multiple Choice

7. Piecewise-Defined Functions

This graph represents the observed and forecasted weekly deaths by COVID-19 in the United States. Why is the graph piecewise-defined?

• The rate of weekly deaths depends on which month of the domain you are looking at.

• Each input is assigned to exactly one output.

• There is a common difference between the number of weekly deaths between each month.

Poll
