Question

tentukan nilai limit fungsi aljabar berikut limit x²+4x-5/(x-1) x mendekati 1​

Answer 1

Jawab:

6

Penjelasan dengan langkah-langkah:

lim x->1 x²+4x-5/(x-1)

pakai lhopital

lim x->1 d/dx x²+4x-5/d/dx x-1

lim x->1 2x+4/1

= (2(1)+4)/1

= 6/1 = 6

pakai distributif

lim x->1 (x-1)(x+5)/(x-1)   --> x-1 di eliminasi

lim x->1 x+5

= 1 + 5

= 6
