I\'m having trouble with this problem. Can someone help me!? Thanks! (10)

Find the limit of f(x) = 6x4 + 7X3 + 2/4x5 as x approaches infinity and as x approaches - infinity.

Solution

just ignore everything but the 6*x^4/(4*x^5) because the infinity makes the rest so small in comparison. then simplify to 3/(2*x) which goes to 0 as x goes to infinity or -infinity.
