Math Problem Statement

Choose the correct transformation of y = x^2 to get the graph of f(x) = -3(x - 6)^2 - 2.

Solution

The problem asks how to transform the graph of y=x2y = x^2 to obtain the graph of f(x)=3(x6)22f(x) = -3(x - 6)^2 - 2.

Let’s break it down:

  1. Horizontal Shift: The expression (x6)(x - 6) inside the square means the graph is shifted 6 units to the right.

  2. Vertical Shift: The constant term outside, 2-2, shifts the graph down by 2 units.

  3. Reflection: The negative sign in front of the coefficient 3-3 reflects the graph over the x-axis.

  4. Vertical Stretch: The coefficient 33 means the graph is vertically stretched by a factor of 3.

Therefore, the correct transformation is:

  • Reflect over the x-axis.
  • Compress vertically by a factor of 3.
  • Shift 6 units to the right.
  • Shift 2 units down.

This matches Option C: "Stretch the graph of y=x2y = x^2 by a factor of 6, and shift it 6 units to the right and 2 units down."

Here are 5 questions related to this transformation concept:

  1. What does the coefficient of (xh)2(x - h)^2 represent in general transformations?
  2. How does a vertical reflection differ from a horizontal reflection?
  3. How can you determine the direction of horizontal and vertical shifts?
  4. What effect does a positive or negative value outside the parentheses have on the graph?
  5. How do you identify compression versus stretching from the coefficient?

Tip: Always interpret transformations in order: start with shifts inside the parentheses, then reflections or stretches/compressions, and finally any vertical shifts.
