The domain is x > 0 and the range is y < 0
Sketching the graph of the function
From the question, we have the following parameters that can be used in our computation:

The above function is an exponential function that has been transformed as follows
- Reflected across both axes
- Shifted to the left by 4 units
Next, we plot the graph using a graphing tool by taking not of the above transformations rules
