Math Problem Statement

Graph the inverse of the provided graph on the accompanying set of axes. You must plot at least 5 points.

Solution

To graph the inverse of the given curve, you will need to reflect it over the line y=xy = x. This means that for each point on the original graph, its coordinates (x,y)(x, y) will be swapped to become (y,x)(y, x) in the inverse. Here’s how you can proceed:

  1. Identify Points on the Original Curve: Select a few points on the given graph. For example:

    • Point 1: (0,5)(0, -5)
    • Point 2: (1,3)(1, -3)
    • Point 3: (4,0)(4, 0)
    • Point 4: (6,2)(6, 2)
    • Point 5: (8,4)(8, 4)
  2. Swap Coordinates: For each point (x,y)(x, y) on the original curve, plot the point (y,x)(y, x) to reflect it over the line y=xy = x.

    • Inverse of Point 1: (5,0)(-5, 0)
    • Inverse of Point 2: (3,1)(-3, 1)
    • Inverse of Point 3: (0,4)(0, 4)
    • Inverse of Point 4: (2,6)(2, 6)
    • Inverse of Point 5: (4,8)(4, 8)
  3. Plot the Reflected Points: Mark these new points on the graph and connect them smoothly to mirror the shape of the original graph on the opposite side of the line y=xy = x.

  4. Draw the Inverse Curve: Connect the points in a way that maintains the general shape and curvature of the original graph but mirrored across y=xy = x.

If you need further assistance plotting these points or interpreting this reflection, let me know!


Would you like a more detailed explanation of this process, or do you have any specific questions?

Here are some related questions to expand your understanding:

  1. Why does swapping xx and yy values reflect a point over the line y=xy = x?
  2. How can you determine if a function has an inverse graphically?
  3. What does it mean for a function to be invertible?
  4. How do horizontal and vertical line tests relate to invertibility?
  5. What are the practical applications of finding the inverse of a function?

Tip: When plotting an inverse, always check if the original graph passes the horizontal line test, ensuring each yy-value corresponds to only one xx-value.
