Mark (√) against the correct answer in the following:
has
f(x) = |x|
Now to check the maxima and minima at x =0.
It can be easily seen through the option.
See |x| is x for x>0 and –x for x<0
That is no matter if you put a number greater than zero or number less than zero you will get positive answer.
∴ for x = 0 we will get minima.
