Question 968886
You have to realize that you cannot have
log( minus # ), like say, {{{ log(( -1 )) }}}.
There is no log to a positive base ( like 10 here )
which can possibly give you a negative result.
----------------------------------------
That means {{{ x = -4 }}} is OK, but {{{ x < -4 }}}
is not possible, so
{{{ x >= -4 }}} and {{{ x = -4 }}} is an asymptote
-----------------------------------------
{{{ f(x) }}} can have any + or - value, since logs
can have any value + or -
----------------------------
Domain is {{{ x >= -4 }}}
range is + to - infinity
----------------------
Here's the plot:
{{{ graph( 400, 400, -5, 5, -5, 5, log( 10, x+4 ) ) }}}
