What do you mean by this?
Every single one of those expressions factor. When factored, this is what we have:

. After canceling out like factors, what we are left with is this:

. That means that b = 9, c = 1, and d = -2
Answer:
-g(x), g(2x), g(-x)
Step-by-st-ep explanation:
if f (–x) = f (x), so all of the signs are the same
you can also try on desmos, the graph is more helpful than words explain sometimes
I think it’s probably c d=2 -10
