Which of the following functions grows the fastest as x goes to infinity? (2 points)

Question

f(x) = ex
f(x) = 2x
f(x) = 4x
f(x) = e-2x

Answer 1

Again, assuming you mean f(x) = e^x, and f(x) = e^(-2x)

using the same webpage as that I gave you in your previous post, change the equations and see what you get.
I hope you would be able to tell that an exponential function would grow the fastest.

Since you titled your posts "Calculus", why not take the derivative of each, and knowing what the first derivative represents should give you the answer.
