Let f: R \\to R be given by f(x)=|x^{2}-1|, x \\inR. then

Correct Answer is : f has a local minima at x = ± 1 and a local maxima at x = 0

f has a local minimum at x = ± 1 but no local maximum

f has a local maximum at x = 0 but no local minimum

f has a local minima at x = ± 1 and a local maxima at x = 0

f has neither a local maxima nor a local minima at any point
