Lim x→5a. -2b.-1c. 1d. 2e. 3

Pake turunan :
Lim x–> 5
1/ -(1/2.(x-4)^(-1/2))
Lim x–> 5
1 / -(1/2/ √(x-4)
masukkin x = 5
1 / -(1/2 / √(5-4)) =
1 / -(1/2 / 1) =
1 / -1/2 =
-2

pake tanjakan
Lim x–> 5
((x-5) / (1-√(x-4)). (1+√(x-4) / (1+√(x-4))
Lim x–> 5
(x – 5) (1+√(x-4) / (1-(x-4))
Lim x–> 5
(x – 5) (1+√(x-4)( / (-x+5)
Lim x–> 5
(x-5) (1+√(x-4) / -1(x-5)
coret (x-5)
Lim x –> 5
(1+√(5-4) / -1 =
(1+1)/-1 =
2/-1 =
-2
