Evaluate the limit. ( a) lim X -> -2 (e-2X - 4x ) ( b ) lim X -J 2 ( 2X2 - Cos ( 3 51 ) ) ( c ) lim 4 x2 - 16 x -) 4 X2 - 6x+ 8 2 find all values of a where the fonction is not continuous and whether its continuous from the left, night or neither. f ( x ) - 4 x- 6 if x 24 X 2 - 4 if 2 4 x 6 4 3 - X XL2
