jika lim (1/f(x) + g(x)) =6 dan lim (g(x) – 1/f(x)) =-4. maka nilai dari lim x mendekati c (f(x).g(x)) =…

Jawaban:
lim(x->a) f(x) =p
lim(x – a) g(x) =q
.
i) lim(x->a) f(x) – 3g(x)=2–>p – 3 q = 2
- ii) lim(x–>a) 3 f(x) + g(x) = 1––>3p + q = 1
Penjelasan dengan langkah-langkah:
p – 3q = 2–>p = 3q ke 2 ke 3p + q = 1
3(3q + 2) + q = 1
9q + 6+ q = 1
10q = – 5
q = 1/2..
.
p = 3q + 2
p = 3 (-1/2) + 2
p = 1/2
.
limit (x-a) f(x). g(x) = p.q = (1/2) (1/2) = – 1/4
