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.

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:
b)
Step-by-step explanation:
4X1 + 3X2 less than or equal to 150
The absolute value of 3 =3
So 3-7= -4
Answer:
3 k^3
Step-by-step explanation:
3(k x k x k)
k*k*k = k^3
3(k x k x k) = 3 k^3
The answer is between B and C but... I'm kinda leaning more towards B but, you choose which one you think is right.
Hope I helped you. :)
