ƒ : (x, y) -> (x+2, y-1)
In terms of a curved line y=2^x,
y+1 = 2^(x-2), therefore y = 2^(x-2) - 1
---------------------------------------------
I don't get the intuition behind this problem.
Why does the equation change from y to y+1, and 2 raised up to x power to 2 to (x-2) power,
if the line clearly shifts to the negative direction (-1) in the y axis and positive (+2) in the x axis?
I hope I'm making myself clear.
