Positive, Hope this helps :)

If your line is slanting down to the left it is negative

Answer:

Step-by-step explanation:

It would be positive because if it were undefined it would be going up and down and the line “test” would work on it but if it were negative it would be going down from the y axis and zero would just a horizontal line

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

Answer:

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

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)
