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. The images referred to herein are available (click) here 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.

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. 4. Double-Check Calculations: For profit and cost-based problems, verify units and numerical computations. 5. Final Notes The WGU Applied Algebra exam emphasizes practical application and data interpretation. Prioritize understanding graphical behaviors, interpreting trends, and applying algebraic models to real-world problems. Consistent practice with online tools and sample problems will build your confidence and accuracy. Good luck!
