do you see the practice questions on here?

Solution

Yes, I can see the practice questions in the document you uploaded. These questions cover topics such as linear equations, exponential functions, interpreting function notation, and analyzing real-world situations using mathematical models. Here are some of the questions mentioned:

  1. Gift card balance: Finding the equation of a line that represents the remaining balance on a gift card based on the number of visits to a restaurant.
  2. Airplane distance: Determining whether the distance of an airplane from the airport is a linear function.
  3. Population growth: Defining a function for deer population growth in a park using exponential functions.
  4. Investment options: Comparing two investment options and determining which is better.
  5. Tub water levels: Deciding whether the height of water in different bathtubs as they drain is best modeled by linear, exponential, or neither functions.

Let me know if you'd like more detailed explanations or solutions to any of these problems.

Would you like more details on any specific question? Here are five related questions to help you expand your understanding:

  1. How do you find the slope and intercept from a word problem, and what do they represent?
  2. How do you determine if a function is linear or exponential from a table of values?
  3. What is the formula for compound interest, and how is it different from simple interest?
  4. How can you tell if a relationship in a real-world problem represents a function?
  5. What are the steps to compare two different investment formulas?

Tip: When modeling real-world problems, always pay attention to the units and context of the problem, as they will guide your interpretation of slope and intercepts.
