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 shown on the right and two transformations defined:
Part (a):
This transformation involves a series of steps:
- Horizontal shift: The term indicates a shift of the graph 2 units to the left.
- Vertical stretch and reflection: The coefficient means the graph is vertically stretched by a factor of 2 and reflected over the x-axis.
- Vertical shift: The term means the graph is shifted down 3 units.
Part (b):
This transformation reflects the graph of 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:
- How does reflecting a graph over the x-axis affect its shape?
- What effect does shifting a graph left or right have on its equation?
- How do we interpret vertical stretching and compressing in transformations?
- How does adding or subtracting constants outside a function affect its vertical position?
- 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).
