Find the indicated limit or state that it does not exist. 20) lim (6x2 - 2x - 5) x--2 21) lim X2 +7x - 18 x-2 x2 - 4 Solve the problem. 22) Evaluate lim Vx - 3 x -9 x-9 23) lim x - 3 x-3 x - 3 Find the limit. 24) Let lim f(x) =4 and lim g(x) =-1. X--10 X--10 Find lim -9f(x) - 10g(x) X--10 g(x) - 10 25) lim sin x x-0 7x Give an appropriate response. 26) Find the limit of f(x) as x approaches 1 from the right. 2 if x 3 Use the properties of limits to help decide whether the limit exists. If the limit exists, find its value. 27) lim -2x2 + 3x - 9 -3x2 + 2 28) lim 4x3 + 10x X-+00 2x4 + 3x3 +4 29) lim 6x/ - x + 3 x-00 9x4 - x - 6
