Consider the function \(f\left( x \right) = \frac{{\left| x \right|}}{x}:\)
a) \(\mathop {\lim }\limits_{x \to {0^ + }} f\left( x \right) = 1\)
b) \(\mathop {\lim }\limits_{x \to {0^{ -}}} f\left( x \right) = - 1\)
c) \(\mathop {\lim }\limits_{x \to 0} f\left( x \right)\) does not exists
1
All (a), (b) and (c) are true
2
Both (a) and (b) are false
3
(c) alone true
4
(a) and (c) are true
