In general, you can translate the graph of a function to the right (+x direction) by h if you transform the function from f(x) to f(xh).
A reflection about the xaxis is done by transforming from f(x) to f(x).
A stretching by a factor of k in the ydirection requires a transformation of f(x) to k.f(x). For example, a stretching of twice in the ydirection would require a transformaton from f(x) to 2f(x).
The given transformation is a combination of all of the three transformations above.
