Question 212303
 
I'm not having any luck getting my graphing calculator to work with log function. Is there any easier way to work these?
------------------
{{{y = log(5,-x)}}}
To have a logarithm, a number has to be greater than zero.
In this case, -x has to be greater than zero, so x has to be less than zero.
Graphing calculators may not be equipped to handle that.
