f(x) = |x| hasA. minimum at x = 0B. maximum x = 0C. neither a maximum

1.	f(x) = \|x\| hasA. minimum at x = 0B. maximum x = 0C. neither a maximum nor a minimum at x = 0D. none of these
Answer» 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.

Answer»

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.
