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 h(x)h(x) in terms of g(x)g(x), where h(x)h(x) is:

  1. Flipped over the x-axis, and
  2. Twice as wide as g(x)g(x).

Solution:

  1. Flipping over the x-axis means multiplying the function by 1-1. So, flipping g(x)g(x) would give g(x)-g(x).
  2. Twice as wide means a horizontal stretch, which is done by replacing xx with x2\frac{x}{2}. This stretches the graph horizontally by a factor of 2.

Thus, the function h(x)h(x) is given by: h(x)=g(x2)h(x) = -g\left(\frac{x}{2}\right)

This satisfies both the conditions of flipping over the x-axis and being twice as wide.

Relative questions:

  1. What happens to the graph of g(x)g(x) when it's flipped over the y-axis?
  2. How would the function change if it was flipped over both the x-axis and the y-axis?
  3. What effect does compressing a function by a factor of 2 have on its graph?
  4. How does the transformation g(kx)g(kx) affect the graph when k>1k > 1 or 0<k<10 < k < 1?
  5. What happens to the domain and range of g(x)g(x) 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.
