Which of the following options is an equivalent function to f(x) = 3(2)3x?
f(x) = 3(8)x
f(x) = 24x
f(x) = 27(8)x
f(x) = 3(8x)

YES LOL IS IT RIGHT?

- Astrophysics

Are they all exponents?

- Astrophysics

You need to learn to put your answers right, if the function has exponents you put this little hat, 34x^2 like that, if it doesn't you put just x, we can't read minds.

- anonymous

oh okay i know now for the next time

- Astrophysics

Ok so fix it now

- anonymous

f(x) = 3(8)^x
f(x) = 24^x
f(x) = 27(8)^x
f(x) = 3(8x)

- Astrophysics

And the original?

- anonymous

yes

- Astrophysics

I mean, is what we're looking for related to f(x) = 3(2)3^x or is that just x..

- anonymous

f(x) = 3(2)^3x

- Astrophysics

ok so its \[f(x) = 3(2)^{3x}\]

- anonymous

ok so, thats the answer?

- Astrophysics

Well this isn't how it works, I will not give you the answer, because when it comes to your tests you will have no idea what you will be doing, like I said earlier you can graph these out yourself, but I know you won't do that.
So I'll just leave you with this image and you can figure it out. |dw:1436408034241:dw| these are all the functions and this is the original, you can try figuring out what is going on here. |dw:1436408096675:dw|

I DONT KNOW HOW?

- anonymous

OH wait, the answer its f(x)= 3(8x)?

- Astrophysics

I think you should really review your exponent rules, because you don't even need graphs for this problem \[f(x) = 3(2)^{3x} \implies 3(8)^x\]

thank you

real numbers

- anonymous

s not positive i see negatives

- anonymous

thank you so much! so the answer its C?

- anonymous

All real numbers?

- anonymous

yes your right let me know if you got it right !

- anonymous

yes it is thank you so much!! you're awesome

@nerlineg

- anonymous

if i was to guess ill pick B

- anonymous

was that right?

- anonymous

I THINK IS D

- anonymous

I CHOOSE THAT

- anonymous

did you get it right?
