Step-by-step explanation:
To transform the graph of into
the following steps are fulfilled:
1) Move the graph 2 units to the right:
Let then
Notice that the cut point has been moved to x = 2.
2) Reflect on the x axis:
To reflect a graph on the x-axis we do Then
3) Stretch according to factor 2.
For this we do
Then we have
4) Move up the graph in two units:
We do
Then
These steps coincide with those listed in the last option. Therefore the correct option is the last one.
"Translate 2 units on the right, reflect on the x-axis, stretch according to the factor 2 and translate 2 units"
