(a) $\lim _ { x \rightarrow - 1 ^ { - } } f ( x )$
(b) $\lim _ { x \rightarrow - 1 ^ { + } } f ( x )$
(c) $\varliminf _ { x \rightarrow - 1 } f ( x )$
(d) $\lim _ { x \rightarrow 1 ^ { - } } f ( x )$
(e) $\lim _ { x \rightarrow 1 ^ { + } } f ( x )$
(f) $\lim _ { x \rightarrow 1 } f ( x )$
(g) $\lim _ { x \rightarrow 2 ^ { - } } f ( x )$
(h) $\lim _ { x \rightarrow 2 ^ { + } } f ( x )$ (i) $\lim _ { x \rightarrow 2 } f ( x )$
(j) f (-1)
(k) f (0)
(l) f (1)
(m) f (2)
