Find limx→−∞(x−1)2x+1
If I divide whole expression by maximum power i.e. x2 I get,limx→−∞(1−1x)21x+1x2
Numerator tends to 1 ,Denominator tends to 0
So I get the answer as +∞
But when I plot the graph it tends to −∞
What am I missing here? "Can someone give me the precise steps that I should write in such a case." Thank you very much!
NOTE: I cannot use L'hopital for finding this limit.
Answer
Hint: Write x2(1−1x)2x(1+1x)
