Explanation Definition used: Improper integral: “If f is continuous on ( − ∞ , b ] , then ∫ − ∞ b f ( x ) d x = lim a → − ∞ ∫ a b f ( x ) d x . If it is exist and finite, then it is convergent otherwise divergent.” Theorem used: Fundamental Theorem: “Let f be a continuous function on [ a , b ] . If F is anti-derivative of f on [ a , b ] , then ∫ a b f ( x ) d x = F ( b ) − F ( a ) .” Calculation: The given improper integral is ∫ − ∞ 0 x x 2 + 3 d x . The integrand f ( x ) = x x 2 + 3 is finite on the unbounded interval ( − ∞ , 0 ] . Find the limit of the given improper integral to check whether it is convergent or divergent
