<p>it shows a graph and equation that follows and you're supposed to identify the new graph based on the equations. btw, i HATE function problems...... an explanation would be greatly appreciated. thanks.</p>
<p>Alright, all that happens is that the graph is moved. There are reasons as to why this happens graphically, but it might be easier to just memorize a few common movements.
As compared to f(x):
f(x - 1) moves the graph one unit to the right
f(x + 1) moves the graph one unit to the left
f(x) + 1 moves the graph one unit up
f(x) - 1 moves the graph one unit down</p>
<p>So in this case, f(x + 2) moves the graph two units to the left</p>
