2. Use a graph and complete the table to investigate the value of the following limits. (Calculator) a ) x2 - 4 lim X 1 x-1x-1 f (x ) b) x2+ 4x + 3 lim X -3 X- - 3 x2 - 3 f (x ) C) x3 - 8 X 2 lim x-2 x- 2 f (x ) 3. Determine whether each statement about the graph of f (x) below is True or False. a) lim f(x) = 1 f) lim f(x) = 1 x - -1+ x-1+ lim f (x) = DNE g) lim f(x) = DNE
