Question -
Answer -
The given function is f(x)= x2 − x + 1.
The point
divides the interval (−1,1) into two disjoint intervals i.e.,
Now, in interval
Therefore, f isstrictly decreasing in interval
However, in interval
Therefore, f isstrictly increasing in interval
Hence, f is neitherstrictly increasing nor decreasing in interval (−1, 1).
