7. Use the facts and graph below to write the equation for g(x)

Step 1: Start with the equation f(x) = |x|. Write the equation for the graph of g(x) that has been stretched vertically by a factor of 2.
Step 2: Use the equation you wrote in Step 1. Write the equation for the graph of g(x) that has also been reflected, or flipped, over the x-axis.
Step 3: Use the equation you wrote in Step 2. Write the equation for the graph of g(x) that has also been shifted down 3 units.
Step 4: Use the equation you wrote in Step 3. Write the equation for the graph of g(x) that has also been shifted right 1 unit.

Answer:

  1. g(x) = 2|x|
  2. g(x) = -2|x|
  3. g(x) = -2|x| -3
  4. g(x) = -2|x -1| -3

Explanation:

1. Multiplying the function by a constant stretches the graph by that constant. Here, you want a stretch factor of 2, so you have ...

g(x) = 2f(x) = 2|x|

__

2. Negating a function causes its graph to be reflected over the x-axis. That makes your second function look like ...

g(x) = -2|x|

__

3. Subtracting 3 from the function value shifts its location on a graph down by 3 units. Your third function will be ...

g(x) = -2|x| -3

__

4. Subtracting a constant from the x-value causes the graph of the function to be shifted right by that amount. Here you want a right shift of 1 unit, so your function is ...

g(x) = -2|x -1| -3
