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.

EXPLANATION
When x=6 and y=13 x+y = 6 + 13 = 19
x + y = 19
Answer: 66
Step-by-step explanation:
6+4^3-8÷2
4^3 = 64
6+64-8÷2
70-8÷2
70-4 = 66
Answer: NOT POSSIBLE
Step-by-step explanation:
It is not possible for such a triangle to be formed because it violates the <em>Triangle Inequality Theorem </em>which states that the sum of two sides of a triangle must be more than the third side.
8 + 4 = 12 which is larger than the other side of 4cm so this is fine
4 + 4 = 8 is equal to the other side of 8cm so this is not fine.
So long as the summed length of any 2 of the sides is not more than the third side, a triangle cannot be formed.
