Math Problem Statement

Transform the graph of y = 1/x^2 to create the graph of y = -1/x^2 + 4.

Solution

The image shows the following instructions:

  • A graph of the function y=1x2y = \frac{1}{x^2} is displayed.
  • The task is to transform this graph to create the graph of the function y=1x2+4y = -\frac{1}{x^2} + 4.

Steps to transform the graph:

  1. Reflection: The graph of y=1x2y = \frac{1}{x^2} will be reflected over the x-axis due to the negative sign in front of 1x2\frac{1}{x^2}. This changes the graph to y=1x2y = -\frac{1}{x^2}, making the curve open downwards instead of upwards.

  2. Vertical Translation: The term "+4" translates the entire graph of y=1x2y = -\frac{1}{x^2} vertically by 4 units upwards. As a result, the vertex of the graph, previously located at (0,0)(0,0), will move to (0,4)(0,4).

Final Transformation Summary:

  • The graph of y=1x2+4y = -\frac{1}{x^2} + 4 is a downward-facing curve with its highest point at y=4y = 4. The asymptotes remain the same: a vertical asymptote at x=0x = 0 and a horizontal asymptote at y=4y = 4.

Would you like a detailed step-by-step graphing process for this transformation or any other details?

Here are 5 related questions for further exploration:

  1. How do horizontal shifts affect the graph of a rational function like 1x2\frac{1}{x^2}?
  2. What happens if you add a constant inside the denominator, i.e., y=1(xc)2y = \frac{1}{(x - c)^2}?
  3. How would the transformation change if the function was y=1x3y = \frac{1}{x^3}?
  4. How do vertical asymptotes behave under different transformations?
  5. What role do reflections play in graph transformations for rational functions?

Tip: Always look at both vertical and horizontal asymptotes when analyzing transformations of rational functions.
