Infinity over Infinity
To solve this indeterminate form, different types of functions must be considered.
Divide all the addends that have the highest exponent by x.
This indeterminate form can be solved another way but the following must be taken into account:
1 If the numerator and denominator have the same degree, the limit is the quotient of the coefficient of powers of the highest grade.
2If the numerator has a higher degree than the denominator, the limit is ± ∞ (depending on the sign of the coefficient of highest degree).
3If the denominator has the highest degree, the limit is 0.
For exponential functions, divide by the highest exponential base.
