Your answer to "d" is incorrect: the answer is

What f(-x) means is wherever you see an "x" in the original equation put (-x) and then simplify.

Your answer to "e" is correct.

What -f(x) means is that you muliply the enitre equation by -1 and then simplify: like this

I will let you do the work.

-- by the way, this isn't a trig problem.
