If you remember that in your coordinate system f(x) = y, -f(x) = - y. So you just make all of the y values negative. Which in practice means you reflect it around the x axis.

Anything to do with the inside of the brackets changes the x co-ordinates and anything outside of the brackets, such as -f(x), changes the y co-ordinates.

reflection in the x axis... so in a way- imagine it on your hand and then flip it to the other side of the axis!
