This would be the set of rational numbers.
When dealing with money, we deal with parts of dollars, written as decimals. Decimals can be written as fractions, so these are rational numbers.
5x^3 - 5x - 8 + 2x^3 + 4x + 2
7x^3 - x - 6 (some like terms)

Answer: -x²+4x-9
Step-by-step explanation:
(g-h)(x) is the same as g(x)-h(x). Since we were given g(x) and h(x), we can subtrac them.
2x-1-(x²-2x+8) [distribute -1]
2x-1-x²+2x-8 [combine like terms]
-x²+4x-9
Now, we know thhat (g-h)(x)=-x²+4x-9.
F(g(x)) where you see an 'x' in f(x) put a g:
f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!
I let the second one for you. Sorry if you disagree!
