Question

Evaluate the limit 9n^3 + 5n - 2/2n^3

Answer 1

9/2 if n goes to infinity and that the 2n^3 is under the whole expression

Explanation:

Let me clear this .

find limit (9n^3 + 5*n - 2)/ (2n^3)

as n --> infinity

Did I put the parentheses in the right spot?

because if you leave it the way you did, then the whole expression goes to positive infinity as n goes to infinity But I will do this with parentheses

so

find limit (9n^3 + 5*n - 2)/ (2n^3)

simplify expression

limit (9/2) + 5/(2n^2) - 1/(n^3)

= (9/2) + 0 - 0

= (9/2)
