Find the following limits or explain why the limit does not exist. Show all steps. x + 2 a. lim x+ 2 x + 5 b. lim x² + 4x + 3 x 2 x² + 6x + 52 Determine if lim f(x) exists. Is the function continuous at x = 1? x→1 f(x) = { 4-3x x² if x < 1 if x > 1 Find the following limits or explain why the limit does not exist.
