Answer:
The parent function is F(x)= x. Whenever it is shifted up or down, you just add (or subtract) that at the end. So it would be f(x)= x - 1. Then it says stretched vertically. If it is stretched vertically, you multiply x by that number. If it is stretch horizontally, you mulitply by the fraction of 1/ that number. In this case it is stretched vertically, so we will use two. Your final answer would be f(x)= 2x - 1
