Math Problem Statement

The graph of f(x) is shown, and two transformations are given: g(x) = -2f(x + 2) - 3 and h(x) = f(-x).

Solution

To analyze the problem, we have the graph of f(x)f(x) shown on the right and two transformations defined:

  1. g(x)=2f(x+2)3g(x) = -2f(x + 2) - 3
  2. h(x)=f(x)h(x) = f(-x)

Part (a): g(x)=2f(x+2)3g(x) = -2f(x + 2) - 3

This transformation involves a series of steps:

  • Horizontal shift: The term f(x+2)f(x + 2) indicates a shift of the graph 2 units to the left.
  • Vertical stretch and reflection: The coefficient 2-2 means the graph is vertically stretched by a factor of 2 and reflected over the x-axis.
  • Vertical shift: The term 3-3 means the graph is shifted down 3 units.

Part (b): h(x)=f(x)h(x) = f(-x)

This transformation reflects the graph of f(x)f(x) across the y-axis.

Steps to graph the transformations:

  • For part (a), take the points on the original graph, shift them left by 2 units, reflect over the x-axis, stretch vertically by 2, and shift down by 3.
  • For part (b), simply reflect all points across the y-axis.

Would you like a more detailed step-by-step guide on how to graph these transformations, or any specific questions about interpreting them?


Here are 5 follow-up questions:

  1. How does reflecting a graph over the x-axis affect its shape?
  2. What effect does shifting a graph left or right have on its equation?
  3. How do we interpret vertical stretching and compressing in transformations?
  4. How does adding or subtracting constants outside a function affect its vertical position?
  5. What happens when a function is reflected across the y-axis?

Tip: Always apply transformations to the graph in the correct order (horizontal shifts, stretches/reflections, and then vertical shifts).
