To get the picture of an inverse, you just take the mirror image over the line y = x.

basic graph of an exponential the graph of an inverse is just the mirror image over y = x

So, the standard graph for a logarithm with a base that's > 1 is

the basic shape of the graph f( x ) = -a^x ... the y-axis is a vertical symptote ... as x gets bigger, the graph climbs slowly

TRY IT:

Draw a rough sketch of
