Answer:
Step-by-step explanation:
Any side to side movement of a function will be reflected inside a set of parenthesis with the x. For example, if the function was a parabola, the parent graph could be, very simply,

Side to side movement would make the equation look like this:

where h is the x coordinate of the vertex.
Up or down movment would make the equation look like this:
for movement upwards, or
for movement downwards. The k represents the y coordiante of the vertex in this parabola.
Because our function has NO numbers inside the parenthesis with the f(x), but it has a -1 after, we are moving the parent graph of this function, whatever it is, down one from its starting position.

Proof provided in the explanation.
Step-by-step explanation:

I'm going to rewrite that middle term so I can apply Pythagorean Identity,
:


Use
:
![\cos^4(\theta)-[1-2\cos^2(\theta)+\cos^4(\theta)]+1](https://tex.z-dn.net/?f=%5Ccos%5E4%28%5Ctheta%29-%5B1-2%5Ccos%5E2%28%5Ctheta%29%2B%5Ccos%5E4%28%5Ctheta%29%5D%2B1)
