Question

Use graphs to determine which of the functions f(x)=2x^2 and g(x)= x^3 /3 is eventually larger( that is, larger when x is very large)

Answer 1

what do you mean by larger wen x is very large...

Answer 2

no need to graph. cubes get larger than squares

Answer 3

g(x)= (x^3)/3 is large when x gets larger

Answer 4

ohh

Answer 5

cubes?

As you can see from here: http://www.wolframalpha.com/input/?i=2x^2%2C+%28x^3%29+%2F+3

g(x) gets larger for a very large x, i.e. when for x > 6

Answer 6

almost looks like this
