Observe the graph:

Consider the scale on about $\"\"$ and $\"\"$ is $\"\"$ units.

The graph is a translation of the graph of $\"\"$ reflected about $\"\"$ -axis and right by $\"\"$ unit.

Tranformation and reflection: $\"\"$ reflected about $\"\"$ -axis of the graph of the function $\"\"$ and translation right by $\"\"$ units.

So, the equation is $\"\"$ .
