Graph:
Now graph the functions
Interpretation:
Below are the steps to transform
Step 1: Shift the base graph by 2 units to the right after vertically shrinking (1/2) times and then taking the reflection about x- axis. .
Step 2: Then shift the obtained graph by 3 units vertically downwards.
Conclusion:
So, by following the above steps, the graph of
