We assume you mean
.. f(x) = -3*x^3 -2
.. g(x) = -3*x^-3

Then
.. f(-3) = -3*(-3)^3 -2 = -3*(-27) -2 = 81 -2 = 79

.. g(4) = -3*4^-3 = -3/64

It is helpful if you use ordinary lower-case letters for variables (except in some formulas where upper-case letters are used). The symbol "×" is used to signify multiplication, so leads to confusion when you try to use it for a variable. In plain text, the exponentiation operator is a caret (^), so x^2 means "x squared", for example. If the exponent is supposed to include an arithmetic operation, then it needs to be enclosed in parentheses, x^(3y-4), for example.

I need help with this:
Brut [27]
By the commutative property of addition, the answer you got
  c = -b+5a
is identical to selection ...
  D. c=5a-b



The commutative property tells you the order of addition doesn't matter, so
  (-b)+(5a) = (5a)+(-b) = 5a-b
(This is one of the reasons we study these properties.)
