Math Problem Statement

Combine the functions f(x) = |sin(x)| and f(x) = sin(|x|) with their corresponding graphs.

Solution

Let's analyze the problem you uploaded.

You are asked to match two functions, f(x)=sin(x)f(x) = |\sin(x)| and f(x)=sin(x)f(x) = \sin(|x|), with their corresponding graphs. Here's the breakdown of the two functions:

  1. f(x)=sin(x)f(x) = |\sin(x)|:

    • This graph will have the same shape as the sine function, but all the negative parts of the sine wave will be reflected above the x-axis, making all values non-negative.
  2. f(x)=sin(x)f(x) = \sin(|x|):

    • This function is the sine of the absolute value of xx, meaning it mirrors the sine wave around the y-axis. For negative values of xx, it will behave as if xx were positive.

Now let's compare the graphs:

  • Left graph: The sine wave looks mirrored around the x-axis, with all negative values made positive. This matches the behavior of f(x)=sin(x)f(x) = |\sin(x)|.

  • Right graph: The graph is symmetric around the y-axis, which is the characteristic of f(x)=sin(x)f(x) = \sin(|x|).

Conclusion:

  • Left graph corresponds to f(x)=sin(x)f(x) = |\sin(x)|.
  • Right graph corresponds to f(x)=sin(x)f(x) = \sin(|x|).

Would you like further details on these functions or any follow-up questions?

Here are 5 related questions to expand your understanding:

  1. How does the graph of f(x)=sin(x)f(x) = \sin(x) differ from f(x)=sin(x)f(x) = |\sin(x)|?
  2. What is the period of f(x)=sin(x)f(x) = \sin(|x|)?
  3. How would you graph f(x)=cos(x)f(x) = \cos(|x|)?
  4. What happens to f(x)=sin(x)f(x) = \sin(x) when the absolute value is applied to both xx and sin(x)\sin(x)?
  5. Can you explain how symmetry around the x-axis and y-axis affects the graph?

Tip: When analyzing absolute value functions, observe how they alter both the negative and positive portions of a graph, reflecting or mirroring different parts.
