jika f(x) = 1-x per 2- akarx^2 +3, maka lim x->1 f(x) .. minta tolong ya kak

Langsung aja y

lim (1 - x) / (2 - √x²+3)
x→1

lim (1-x)(2+√x²+3) / (2-√x²+3)(2+√x²+3)
x→1

lim (1-x)(2+√x²+3) / 4-(x²+3)
x→1

lim (1-x)(2+√x²+3) / 1 - x²
x→1

lim (1-x) (2+√x²+3) / (1-x) (1+x)
x→1

lim (2 + √x²+3) / (1 + x)
x→1

= (2 + √1²+3) / (1 + 1)
= (2 + √4) / 2
= 4/2
= 2

semoga berguna +_+
