Question

RULES for Limits

Those rules apply only if its (x---->infinity) or (x---->-infinity) or it can also apply to lets say for example (x---->5) ?


RULES:
(1) if numerator's exponent value is greater then limit approaches infinity
(2) if denominator's exponent value is greater then limit approaches zero
(3) if both numerator and denominator's exponent value are same then limit is the coefficient of highest term in numerator divided by coefficient of highest term in denominator

Answer 3

that's only for x approaching + or - infinity. when it approaches an actual number you can simply plug it in and get a numerical answer that isn't necessarily zero or infinity.

make sure you check the limit from the left and right side of numbers like 5 :)

ok brotha!
