Exponential functions.

OpenStudy (anonymous):

\[f(x)3^{x-3}\] Can you use any points to graph it?

OpenStudy (zzr0ck3r):

\(f(x)=3^{x-3}\) Are you asking what the domain is?

OpenStudy (anonymous):

im just trying to figure out how to graph it. with x and y points.

OpenStudy (zzr0ck3r):

put in an \(x\) value, and you get out the \(y\) value.

OpenStudy (anonymous):

it can be any x value right?

OpenStudy (zzr0ck3r):

yes, the domain is all real numbers

OpenStudy (anonymous):

Like for example -2 it would be 3^-2-3?

OpenStudy (zzr0ck3r):

correct

OpenStudy (anonymous):

okay thanks! :)

OpenStudy (zzr0ck3r):

\(3^{-2-3}=3^{-5}=\dfrac{1}{3^5}\)

OpenStudy (anonymous):

thats it? it would be 1/15?

OpenStudy (zzr0ck3r):

what is \(3^5\)?

OpenStudy (anonymous):

ohhh 243

OpenStudy (zzr0ck3r):

then it is \(\dfrac{1}{243}\)

OpenStudy (anonymous):

okay thanks :)
