Math Problem Statement
Let g(x) be some function in the domain (-10, 10). Write a function h(x) in terms of g(x) which is identical to g(x), but is flipped over the x-axis, and is twice as wide as g(x).
Solution
The problem asks you to write a function in terms of , where is:
- Flipped over the x-axis, and
- Twice as wide as .
Solution:
- Flipping over the x-axis means multiplying the function by . So, flipping would give .
- Twice as wide means a horizontal stretch, which is done by replacing with . This stretches the graph horizontally by a factor of 2.
Thus, the function is given by:
This satisfies both the conditions of flipping over the x-axis and being twice as wide.
Would you like more details or have any further questions?
Relative questions:
- What happens to the graph of when it's flipped over the y-axis?
- How would the function change if it was flipped over both the x-axis and the y-axis?
- What effect does compressing a function by a factor of 2 have on its graph?
- How does the transformation affect the graph when or ?
- What happens to the domain and range of after these transformations?
Tip:
When transforming functions, always check how horizontal and vertical stretches or reflections impact the graph, particularly on the domain and range.
