Understanding the Graph of a Function: A Guide to Selecting the Correct Answers

When shopping for accessories for her action camera, Giana found an advertisement for a replacement battery. The advertisement includes the given graph of a function to represent the charge remaining in the battery after a certain period of time. As Giana is trying to make an informed decision, she needs to understand the graph and select the correct answers to ensure she gets the best battery for her needs.

Analyzing the Graph

The graph represents the charge remaining in the battery after a certain period of time. The x-axis represents the time in hours, and the y-axis represents the charge remaining in the battery as a percentage. The graph shows that the charge remaining in the battery decreases over time, with the charge dropping to 0% after 5 hours.

Key Features of the Graph

  • The graph is a decreasing function, indicating that the charge remaining in the battery decreases over time.
  • The graph has a negative slope, indicating that the charge remaining in the battery decreases at a constant rate.
  • The graph passes through the point (0, 100), indicating that the battery is fully charged at the start.
  • The graph passes through the point (5, 0), indicating that the battery is completely drained after 5 hours.

Selecting the Correct Answers

To select the correct answers, we need to analyze the graph and identify the key features. Based on the graph, we can answer the following questions:

  • What is the initial charge of the battery?
    • The initial charge of the battery is 100% at the start, which is represented by the point (0, 100).
  • What is the charge remaining in the battery after 5 hours?
    • The charge remaining in the battery after 5 hours is 0%, which is represented by the point (5, 0).
  • What is the rate at which the charge remaining in the battery decreases?
    • The charge remaining in the battery decreases at a constant rate, which is represented by the negative slope of the graph.
  • What is the time it takes for the battery to be completely drained?
    • The battery is completely drained after 5 hours, which is represented by the point (5, 0).

Conclusion

In conclusion, the graph of the function represents the charge remaining in the battery after a certain period of time. By analyzing the graph, we can identify the key features and select the correct answers. The initial charge of the battery is 100%, the charge remaining in the battery after 5 hours is 0%, the rate at which the charge remaining in the battery decreases is constant, and the time it takes for the battery to be completely drained is 5 hours.

Q&A: Understanding the Graph of a Function

In our previous article, we discussed the graph of a function and how it can be used to represent real-world situations. We analyzed the graph of a function that represents the charge remaining in a battery after a certain period of time. In this article, we will answer some frequently asked questions about the graph of a function.

Q: What is the purpose of the graph of a function?

A: The graph of a function is a visual representation of the relationship between the input and output of a function. It can be used to represent real-world situations, such as the charge remaining in a battery, economic trends, and population growth.

Q: What are the key features of the graph of a function?

A: The key features of the graph of a function include:

  • Domain and Range: The domain is the set of all possible input values, and the range is the set of all possible output values.
  • Intercepts: The x-intercept is the point where the graph crosses the x-axis, and the y-intercept is the point where the graph crosses the y-axis.
  • Slope: The slope of the graph represents the rate of change of the function.
  • Asymptotes: An asymptote is a line that the graph approaches but never touches.

Q: How do I analyze the graph of a function?

A: To analyze the graph of a function, follow these steps:

  1. Identify the key features: Identify the domain, range, intercepts, slope, and asymptotes of the graph.
  2. Determine the type of function: Determine whether the graph represents a linear, quadratic, polynomial, or rational function.
  3. Analyze the behavior of the function: Analyze the behavior of the function as the input values approach positive or negative infinity.
  4. Identify any patterns or trends: Identify any patterns or trends in the graph, such as periodic behavior or oscillations.

Q: What are some real-world applications of the graph of a function?
