Math Problem Statement

Below is the graph of a transformation of the graph of y = x^2. Determine the function graphed after the transformations.

Solution

The graph shown appears to be a transformation of the function y=x2y = x^2, which is a standard parabola. Let’s analyze the transformation based on the options given:

  1. Reflection: The parabola opens downward, so there is a vertical reflection, which indicates a negative sign in front of the quadratic term.
  2. Horizontal Shift: The vertex is shifted from the origin to (2,3)(-2, -3), indicating a horizontal shift to the left by 2 units. This is represented as (x+2)(x + 2) in the equation.
  3. Vertical Shift: The vertex is also shifted down by 3 units, indicating a vertical translation of 3-3.

Now, let’s match this with the given options:

  • The equation should involve a reflection, a horizontal shift left by 2, and a vertical shift down by 3. This matches with the option: y=(x+2)23y = -(x + 2)^2 - 3

None of the given options exactly matches this, but it looks like there may be a typo in the options. Based on the graph and transformation analysis, the correct equation should be:

y=(x+2)23y = -(x + 2)^2 - 3.

Would you like more details or further explanations? Here are some related questions:

  1. How do reflections affect the shape of a parabola?
  2. What does shifting a graph horizontally by 2 units to the left involve?
  3. How do vertical shifts affect the vertex of a parabola?
  4. What would the graph look like if there was no reflection?
  5. How can you tell from the equation where the vertex of a parabola is located?

Tip: Always identify the transformations of the basic function (reflections, shifts, stretches) by analyzing changes to the vertex and orientation of the graph.
