Math Problem Statement

The graph of y = h(x) is shown. Draw the graph of y = 2h(x - 4).

Solution

The problem asks to "Draw the graph of y=2h(x4)y = 2h(x - 4)", based on a given graph of y=h(x)y = h(x). Since I can't see the actual graph of h(x)h(x), I can guide you through the transformation process.

To graph y=2h(x4)y = 2h(x - 4), follow these steps:

1. Horizontal Shift (due to x4x - 4):

  • The expression x4x - 4 indicates a horizontal shift. Specifically, the graph of h(x)h(x) is shifted 4 units to the right. So, every point (x,y)(x, y) on the graph of h(x)h(x) will move to (x+4,y)(x+4, y).

2. Vertical Stretch (due to the coefficient 2):

  • The factor of 2 outside the function indicates a vertical stretch. This means that the graph will be stretched by a factor of 2. In other words, if a point on the original graph of h(x)h(x) is at (x,y)(x, y), it will now be at (x,2y)(x, 2y).

3. Apply both transformations:

  • First shift the graph horizontally by 4 units to the right.
  • Then, stretch it vertically by multiplying all the yy-coordinates by 2.

If you have the graph of h(x)h(x) available, you can apply these transformations directly.

Do you have any questions or would you like more detailed steps?

Here are five questions to expand the concept:

  1. How does the transformation y=h(xc)y = h(x - c) generally affect the graph?
  2. What happens if the function had been y=h(x+4)y = h(x + 4) instead?
  3. How would a negative coefficient, like y=2h(x4)y = -2h(x - 4), affect the graph?
  4. How do you interpret transformations that include both vertical and horizontal shifts?
  5. Can the transformations y=2h(x4)y = 2h(x - 4) be applied in a different order (e.g., vertical stretch first)?

Tip: When applying transformations, always handle horizontal shifts inside the function (involving xx) and vertical changes (like stretching or reflecting) outside the function.
