To find the domain, we find every single value that can exist along the x axis.
One can notice here that w is in the denominator, which means a value doesn't exist at 0, because we can't have 0 in the denominator.
Answer:
(-∞,0) U (0,∞)
 
        
             
        
        
        
Answer: 
Step-by-step explanation:
The standard form of a circle is written as such:

Where (h, k) is the center of the circle, and r is the radius. 
We know that the center is (-7, 0), so we can plug that into the equation like this: 
The radius is 3 * the square root of 3. To square this, we can multiply 3 squared and the square root of 3 squared:

So, your standard form equation is the following:
