Which of the following functions grows the slowest as x goes to infinity?

Which of the following functions grows the slowest as x goes to infinity?

5^x
5x
x^5
They all grow at the same rate.

Answer:

The functions grow from slowest to fastest

linear, polynomial, exponential

a table will show this easily

1 2 3 4
5x 5 10 15 20

x^5 1 32 243 1024

5^x 5 25 125 625

After 5, the exponential starts growing much more rapidly than the polynomial

So much for the spacing -_-
