WGU Applied Algebra (C957) Study Guide

 The WGU Applied Algebra (C957) exam evaluates your ability to interpret and solve
algebraic problems applied in real-world scenarios. The test involves analyzing tables,
graphs, and functions to draw conclusions, make predictions, and solve equations. Below is a
structured guide that I used to effectively prepare.

1. Key Topics and Question Types
A. Interpreting Tables
• Questions often ask you to extract information and compare values from tables.
Example:
"The table shows the profits of a gaming company for each month. What can you
conclude?"
o Practice analyzing trends and identifying maximum or minimum values in
datasets.
B. Graphing Functions
• You must interpret functions presented graphically, including their slopes, intercepts,
and turning points.
Example:
"The profit function P(x)P(x) gives total profit in millions of dollars for xx products.
How should P′(1)P'(1) be interpreted?"
o Tip: Understand derivatives conceptually (e.g., rate of change) even if the
exam doesn’t require calculus-level computations.
C. Real-World Applications of Algebra
• Apply algebraic models to business contexts, such as profit maximization or cost
efficiency.
Example:
"A gas station’s profit model is P(10)=1230P(10) = 1230. What does this mean?"
o Tip: Familiarize yourself with interpreting units and context in algebraic
expressions.
D. Analyzing Rates of Change
• These questions involve determining when values increase, decrease, or plateau.
Example:
"At what time does the number of customers change from decreasing faster to
decreasing slower?"
o Tip: Understand key points on graphs such as inflection points and slope
changes.
E. Comparative Data
• Interpret data trends from charts or tables, comparing values across timeframes.
Example:
"What can be concluded about incomes in 1998 compared to 1994 and 1996?"
o Tip: Use key data points and trends from the graph to justify conclusions.
2. Study Strategies
A. Practice Data Interpretation
• Use datasets and practice extracting insights, such as identifying trends, calculating
changes, and making predictions.
• Key Skill: Pay close attention to units (e.g., dollars, thousands) and ensure
consistency in your calculations.
B. Understand Graphical Representations
• Review how linear, quadratic, and exponential functions behave graphically:
o Linear: Constant rate of change (slope).
o Quadratic: Symmetrical parabola with a vertex (maximum or minimum).
o Exponential: Rapid increase or decrease.
C. Focus on Real-Life Contexts
• Prepare for questions that model profits, costs, or populations, which may require:
o Recognizing variables in equations.
o Connecting slope or derivative meaning to the context (e.g., profit per
product).
D. Solve Practice Problems
• Online Platforms: Use resources like Khan Academy, Mathway, or WGU’s study
materials to access practice problems.
• https://payhip.com/b/kuQJD - Recent past exams on the class. The most realistic
material you can acquire to practice for this course.
• Flashcards: Create flashcards for key terms like slope, intercepts, derivative
interpretation, and rate of change.
3. Recommended Online Resources
1. Khan Academy: Covers algebraic functions, graph interpretation, and real-world
applications.
2. Desmos Graphing Calculator: Practice visualizing equations and interpreting graphs
interactively.
3. Purplemath: Provides simple explanations of algebraic concepts with example
problems.
4. WGU Learning Portal: Review course-specific materials and quizzes for targeted
practice as well as https://payhip.com/b/kuQJD
4. Test-Taking Tips
1. Understand the Question: Identify key details, including units, variables, and the
specific question being asked.
2. Visualize Trends: For graph and table-based questions, sketch the data trend if
necessary to better analyze it.
3. Eliminate Distractors: Narrow choices by removing answers that don’t align with
the graph, table, or equation.WGU Applied Algebra (C957) Study Guide
