Step-by-step explanation:
The value of X in this question is 46
C
Using Descartes' rule of signs
look for the number of sign changes in f(x)
+ / + / - / -
There is 1 sign change hence 1 positive zero
f(-x) = -x³ + x² + 8x - 8
look for the number of sign changes in f(- x)
- / + / + / -
there are 2 sign changes hence 2 possible negative zeros
Answer:
3
Step-by-step explanation:
Ascending order:
4 ,4 , 4 ,4 ,5, 6 ,7 , 7 ,7
9 data: split in
4 ,4 , 4 ,4 | 5 | 6 ,7 , 7 ,7
4 ,4 | 4 ,4 | 5 | 6 ,7 | 7 ,7
(7+7)/2-(4+4)/2
=7-4
=3
