# Thread: exponential & logarithmic functions

1. ## exponential & logarithmic functions

How would I graph parent of:

☆logarithmic function
☆exponential function
in my TI - 83. I need to make sreen-shots proving i used a calculator, but idk what to put in under "y="...

I have the TI-89 but probably the same..
if I understand you question "idk" ???

set it up for split screen mode\f2\split screen
to toggle the apps 2nd\apps

assum you are using a screen shot link to your pc..
if not there are free downloads from TI

hope this helps.

I meant i dont know (idk) what the parent function is, in terms of calculator syntax. for a logarithmic function it's log(x) i think, but what about an exponential function? isn't it y=a^x or something? what do i put it in the calc?

I'd go with $\displaystyle y=e^x$

I've never heard of the "parent function" before. (Other than changing diapers. ) So I Googled it and here is the list I got...
