If we let , then . Recall that f(x) is used in place of 'y'. So what does mean? It simply means . So what we're doing is taking EVERY y coordinate on the graph of and negating it to get a y-coordinate on . Visually, we're reflecting the graph over the x-axis.

Here's the visual:

----------------------------------------------
The basic function is y = e^x and it looks like this:

-------------------------------------------------------
Your function is y = -e^x and it looks like this:

--------------------------------------------------------
Notice that e^x has flipped over the y-axis.
That means it was reflected in the y-axis.
