Answer:
-1.75 and 1.75.
Step-by-step explanation:
Absolute value is the value of a number, disregarding its sign. Absolute value will always be written as positive.
Examples:
The absolute value of 5 is 5.
The absolute value of -9836 is 9836. Not -9836, because absolute value will always be positive.
The absolute value of -2 is 2.
The absolute value of 87 is 87.
And, thus, the absolute value of -1.75 is 1.75, and so is the absolute value of 1.75. -1.75 will be in between -2 and -1.5. 1.75 will be in between 1.5 and 2.

Solution:
The given Polynomial is :
By Rational Root theorem the of Zeroes of the Polynopmial are:
But ,
So, no root of this polynomial is real.
Therefore, All the four roots of Polynomial are imaginary.
So, we can't say whether the number k=2, is an upper or lower bound of the polynomial .
