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:

Answer: This relation is not a function
Step-by-step explanation:
To find out if a relation is a function, we need to use the vertical line test, which means each input value only has one output value. This graph does not pass that vertical line test.
