Question

Find the limit of h(x) as x approaches infinity when h(x)= [f(x)/(x^3)]

Answer 1

ans. depends on f(x)

Answer 2

you just plug in infinity

Answer 3

when I tried to solve it, I got infinity as the answer, but the book says the answer is 5

Answer 4

look if f(x)=5(x^3) then ans. is 5
if f(x) is (x^4) then ans. is infinity..
note in both cases f(x) tends to infinity as x tends to infinity.. so stating the function is also important..

Answer 5

I mean the answer was in the back of the book -_-

Answer 6

the entire problem was stated up top ^^^^

Answer 7

i agree with hantenks you have to know f(x) to take that limit.
