Answer:
Depends on area
Step-by-step explanation:
Area of 1 greater than 2 than 3 than 4
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:
Statements 2 and 3 are true
Step-by-step explanation:
Reading from the table
When x = -4, y = -1 so statement 1 is false
When x = -1, y = -2.5 so statement 2 is true
When x = 0, y = -3 so statement 1 is true
When x = 2, y = -4 so statement 2 is false
