A, it’s the move for that wuestion
Yes it is I’m not sure tho the other person will help
The graph of
is given by,
Here given the function is 
when
, then it passes through the origin (0,0).
When 
Since we know that,
, then the function has maximum height at
.
Again when
, again the function is 0.
So clearly the function is the Oscillating function.
Using graphing calculator we get the graph of function
,

The number of positive roots is the number of changes of signs there are, then decrease by 2 each time and stop when you get to 1 or 0
negative roots, sub every x with -x and reevaluate, count change of signs
decrease by 2 each time and stop when you get to 1 or 0
y=+2x⁵-x⁴-2x³+4x²+x-2
+,-,-,+,+,-
1 2 3
3 or 1 positive roots
replace x with -x ( baically flip all signs of odd powerd numbers)
y=-2x⁵-x⁴+2x³+4x²-x-2
-,-,+,+,-,-
1 2
2 or 0 negative roots
3 or 1 positive roots
2 or 0 negative roots
2nd option is answer
Answer:
Coordinate D. Because D lies on the 2nd quadrant, meaning that x has a negative value whereas y is positive.
