matematika kls 11 bab limit fungsi tolong bantuannya

1. lim
= (-1³)+1/2.(-1²)-2
(-1)+1/2.1(-2) = 0/0

T.L.Hopital
= 3x²/4x
= 3.(-1²)/4.(-1)
=3.1/(-4)
= - 3/4

2.lim = 2²-4/2²-3.2+2
=4-4/4-6+2 =0/0
T. L.hopital
=2x/2x+3
=2.2/2.2+3
=4/7

3.lim = √0+2-√2/0
=√2-√2/0
=0/0
t.l.hopital
√1/1

4.lim = 2/(x-2)-√x²+4x
= 2/√x²-4x - √x²+4x
L = b-q/2√a
L= (-4)-4/2√1
L= -8/2 = -4

5.L = b-q/2√a
L = 2-(-4)/2√1
L = 6/2 = 3

semoga bisa membantu dan maaf jika salah..
