Go through question number 4
The Attempt at a Solution
See basically the question is asking us to find the range of the given function x/(x^2+x+1).
So,I began solving it this way...
I am stuck at this step.
I asked my friend for a hint and he told me to apply the condition that Determinant(D)>=0.
But,I am unable to understand why D>=0?
I will be thankful for help!
