Answer 1

Jawab:

Limit ALjabar

sifat

i) lim (x-> a) f(x)/g(x) =   [ lim x ->a  f(x) ] / [ lim x-> a  g(x)]

ii) lim (x-> a)√{ f²(x)+g²(x)} =   [ lim x -> a √ {f(x)}² + {g(x)}²]

Penjelasan dengan langkah-langkah:

lim(x-> a)  f(x) = -9

lim(x-> 1)  g(x) = -12

lim(x->a)  h(x) = 0

.

lim(x-> a)   { g(x)}/  { 8. f(x) + h(x) }

= { -12 } / { 8. (9)  + 0 }

= - 12 / 72

= - 1/6 (terbukti)

lim (x -> a)  √{ f²(x) + g²(x)}

= √(9² + (-12)²)

= √(81 + 144)

= √225

= 15 (terbukti)
