Math Problem Statement

Each statement describes a transformation of the graph of f(x) = x^2. Which statement correctly describes the graph of the function shown below? g(x) = 3(x - 6)^2 - 4

Solution

Let's examine the function g(x)=3(x6)24g(x) = 3(x - 6)^2 - 4 and determine the correct transformation from the basic function f(x)=x2f(x) = x^2.

  1. Vertical Stretch: The coefficient 3 in front of (x6)2(x - 6)^2 indicates a vertical stretch by a factor of 3. This stretches the graph of f(x)=x2f(x) = x^2 by making it narrower.

  2. Horizontal Translation: The term (x6)(x - 6) indicates a shift to the right by 6 units, as xhx - h inside the square represents a horizontal shift to the right when h>0h > 0.

  3. Vertical Translation: The 4-4 at the end of the equation represents a downward shift of 4 units, as subtracting a constant outside the squared term moves the graph down.

Based on these transformations:

  • The graph of f(x)=x2f(x) = x^2 is vertically stretched, shifted 6 units to the right, and 4 units down.

The correct answer is: C. It is the graph of f(x)=x2f(x) = x^2 vertically stretched, and then translated 6 units down and 4 units to the right.

Would you like further details or have any questions?

Here are some related questions for further exploration:

  1. How do different values of vertical stretches or compressions affect the graph?
  2. What changes would occur if the equation had a negative coefficient instead of positive?
  3. How would the transformation differ if we added a constant inside the squared term?
  4. What are the effects of horizontal shifts on parabolas?
  5. How can we identify transformations just by looking at the equation?

Tip: Always remember that adding or subtracting inside the function (next to xx) affects horizontal shifts, while changes outside the function affect vertical shifts.
