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.
Answer: Raju travels at a higher speed.
Step-by-step explanation:

Speed inversely proportional to time.
As time taken to cover a particular distance decreases the speed will increase.
Raju covers a certain distance in 1 hour.
Sham covers the same distance in 2 hours.
1< 2
Thus Raju travels at a higher speed.
Answer:
d is the answer
Step-by-step explanation:
just read the statements properly
Well its easy mean search a video in YouTube
there are two types for systems of question:
The method for elimination
The method for substitution
The elimination only that u have to do is found x or y hat are the sam,e number with different symbols ↓↓like this↓↓
- 7y + 3x = 45
7y + 12x = 33
the y is cancel and... u know the process..
But the method for substitution is different u only need to put the y en the problem and that's it, and when u found the valor of x u can solve for y ↓↓like this↓↓
4x - 2y = 24
y = x - 5
4 (x - 5) = 24
4x - 20 = 24
+20 +20
4x = 44
4x/4 = 44/4
x = 11
