Math Problem Statement

Label each function as LINEAR or EXPONENTIAL and state if the function will have a constant difference or a constant ratio.

Solution

Here’s the solution for each part of the assessment:

  1. Graph with the curved line:

    • Type: Exponential
    • Reason: Exponential functions show a constant ratio between consecutive values, represented by the steep upward curve.
  2. Table labeled g(x)g(x):

    • Type: Linear
    • Reason: The differences between g(x)g(x) values are constant (8,5,2,1,4,7-8, -5, -2, 1, 4, 7), showing a constant difference.
  3. Table labeled f(x)f(x):

    • Type: Exponential
    • Reason: The f(x)f(x) values double each time (e.g., 61224486 \to 12 \to 24 \to 48), showing a constant ratio.
  4. Equation y=2x+8y = -2x + 8:

    • Type: Linear
    • Reason: Linear equations have the form y=mx+by = mx + b with a constant rate of change (2-2 here).
  5. Recurrence relation f(n)=f(n1)+4f(n) = f(n-1) + 4:

    • Type: Linear
    • Reason: Adding a constant value (+4+4) for every step results in a constant difference.
  6. Equation f(x)=3(2x)f(x) = 3(2^x):

    • Type: Exponential
    • Reason: The function has a base of 22 raised to a power (xx), showing exponential growth with a constant ratio.

Here are 5 related questions to expand your understanding:

  1. What is the general difference between linear and exponential functions?
  2. How can you verify whether a table shows a linear or exponential function?
  3. What happens when the base of an exponential function is less than 1?
  4. How would you describe the graph of a negative linear slope like y=2x+8y = -2x + 8?
  5. Can a recurrence relation represent an exponential function? If so, how?

Tip: To quickly identify an exponential pattern, check for a consistent multiplication factor (constant ratio) between outputs!
