Math Problem Statement

Below is a graph of g(x), a transformation of f(x) = x^2. What is the equation for g(x)?

Solution

The image shows the graph of a transformation of the function f(x)=x2f(x) = x^2, with a new function g(x)g(x). Based on the graph, it seems that the function g(x)g(x) represents a horizontal shift of the original function f(x)=x2f(x) = x^2.

Here’s the breakdown:

  1. The vertex of f(x)=x2f(x) = x^2 is originally at (0,0)(0, 0).
  2. In the graph provided, the vertex of g(x)g(x) appears to be at (3,4)(3, 4).

This suggests a horizontal shift 3 units to the right and a vertical shift 4 units upwards. Therefore, the transformation applied to f(x)f(x) can be written as:

g(x)=(x3)2+4g(x) = (x - 3)^2 + 4

This equation represents the function that has been shifted horizontally and vertically.

Would you like a detailed explanation of how these transformations work?

Here are 5 related questions to expand your understanding:

  1. What happens to the graph of f(x)=x2f(x) = x^2 if you shift it left by 2 units?
  2. How does a vertical stretch affect the function f(x)=x2f(x) = x^2?
  3. What is the equation of f(x)=x2f(x) = x^2 if the graph is reflected over the x-axis?
  4. How do you find the vertex of a transformed quadratic function?
  5. What is the effect of adding a coefficient in front of (x3)2(x - 3)^2 on the graph?

Tip: When dealing with transformations, horizontal shifts involve changes inside the parentheses (i.e., (xh)(x - h)), while vertical shifts affect the constant outside (i.e., +k+ k).
