ANSWER
EXPLANATION
There are many transformation of function f(x)
The first transformation is an horizontal translation 3 units to the right: f(x - 3)
The next transformation is a dilation by a factor of 2: 2f(x-3)
The next one is a reflection over the x-axis: -2f(x-3):
And finally there's a translation 1 unit up: -2f(x-3) + 1
