Math Problem Statement

Graph the following function: g(x) = |x| + 5

Solution

The given function is g(x)=x+5g(x) = |x| + 5.

This is an absolute value function with a vertical shift. Here's how to analyze and graph it:

Step-by-step breakdown:

  1. Absolute Value Function:

    • The basic absolute value function is f(x)=xf(x) = |x|, which has a "V" shape, with the vertex at the origin (0,0). It opens upward.
  2. Vertical Shift:

    • The +5+5 at the end of the function means that the graph is shifted up by 5 units. So instead of the vertex being at (0, 0), it is now at (0, 5).

Key Points:

  • Vertex: (0, 5)
  • The graph will be symmetrical about the y-axis because of the absolute value.
  • The slope of the "arms" of the "V" is 1 and -1 on either side of the vertex.

Sketch of the Graph:

  • The graph will look like a "V" shape starting at the point (0, 5) and going up.
  • For x>0x > 0, the slope is 1, meaning the graph increases as xx increases.
  • For x<0x < 0, the slope is -1, meaning the graph decreases as xx becomes more negative.

If you'd like, I can generate a graph for you.

Would you like more details on this or have any questions?

Here are 5 related questions to expand on this:

  1. What happens to the graph if we change the vertical shift to -5?
  2. How would adding a horizontal shift affect the graph?
  3. Can you identify the domain and range of g(x)=x+5g(x) = |x| + 5?
  4. What if we multiply the absolute value by a constant (e.g., g(x)=2x+5g(x) = 2|x| + 5)? How does this change the graph?
  5. How do you solve equations involving absolute value functions, such as x+5=8|x| + 5 = 8?

Tip: Always look at how the absolute value shifts and stretches to quickly understand changes to its graph.
