Answer:
(b) {-8, 2}
Step-by-step explanation:
The given equation
x³ +6x -16 = 0
cannot be factored in integers. It has one irrational real root near x=1.759, and two complex roots.
__
Perhaps you want to factor ...
x² +6x -16 = 0
(x +8)(x -2) = 0
This has solutions x = -8 and x = 2 that make the factors be zero.

Answer:
Step-by-step explanation:
By definition, the derivative of is given by:
Given ,
must also be
. Therefore, we have:
Note that the derivative of a constant is always zero since for , where
is some constant,
and we obtain
in the numerator, yielding a final answer of zero.
