Question

Cum se face acest exercitiu, ma incurca acel a de la numarator.

Answer 1

a) asimptota vertical x=1
b) asimptota oblica la +∞
m=lim cand x->∞f(x)/x=lim cand x->∞(x²+a²x+b)/(x²-x)=1

n= lim x->∞ ((x²+a²x+b-x*x+x)/(x-1)=
n= lim x->∞(x(a²+1)+b)/(x-1)=a²-1

y=mx+n=x+(a²+1)≡bx+2

b=1
a²+1=2

a²=1 ⇒a=+-1∩
