Answer:
D
Step-by-step explanation:
To check whether a function is odd or even, we simply substitute the argument by its negative version, namely "x" by "-x".
if the expression simplifies to resemble the original expression, that simply means the expression is
even. If it resembles the original negative expression, is
odd.
![\bf g(x)=-2x^3-9\\\\ -------------------------------\\\\ \stackrel{x=-x}{g(-x)}=-2(-x)^3-9\implies g(-x)=-2(-x)(-x)(-x)-9 \\\\\\ g(-x)=+2(x)(x)(x)-9\implies g(-x)=2x^3-9](https://tex.z-dn.net/?f=%5Cbf%20g%28x%29%3D-2x%5E3-9%5C%5C%5C%5C%0A-------------------------------%5C%5C%5C%5C%0A%5Cstackrel%7Bx%3D-x%7D%7Bg%28-x%29%7D%3D-2%28-x%29%5E3-9%5Cimplies%20g%28-x%29%3D-2%28-x%29%28-x%29%28-x%29-9%0A%5C%5C%5C%5C%5C%5C%0Ag%28-x%29%3D%2B2%28x%29%28x%29%28x%29-9%5Cimplies%20g%28-x%29%3D2x%5E3-9)
well, that doesn't look like the original
- 2x³ - 9, so is not
even.
and -f(x) would be
2x³ + 9, and that doesn't look like either, so is not
odd.
thus is neither.
Answer:
2.96
Explanation:
37/x=100/8
(37/x)*x=(100/8)*x - we multiply both sides of the equation by x
37=12.5*x - we divide both sides of the equation by (12.5) to get x
37/12.5=x
2.96=x
x=2.96
The answer is 3
hope this helps :)
