Equation in comments.

anonymous · Answer

which one???

anonymous · Answer

$$u(x)=(1/6)^{x}  $$  Or $$v(x)=6^{x}$$

hero · Answer

Which do you believe is correct? @laurenbae

anonymous · Answer

i don't know that's why i asked lol

anonymous · Answer

if i had to guess maybe the first one...

hero · Answer

Why would you choose the first one? The first one has a "fraction" as its base.

anonymous · Answer

like i said...it was just a guess...i don't know how to figure this out.

hero · Answer

There are two ways you can figure it out:

1. Algebra
2. Graphing (by hand or electronically)

hero · Answer

To do it using algebra, keep choosing larger and larger values of x, and substitute those values for x into each formula to see what happens. Normally, you would start with values like x = {0,1,2,3} and compare results.

hero · Answer

For example, if we said that x = 3, substituting that into each formula would produce: 

$u(3) = (\frac{1}{6})^3 = \frac{1}{216}$

$v(3) = 6^3 = 216$

hero · Answer

Clearly, 216 > 1/216

hero · Answer

If you decided to plot both on a graph you would end up with:

|dw:1343632168741:dw|
