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

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

Step-by-step 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)

make sure you have version 2.50

try looking in the very back of the book : )
