Yes, this is a function. Domain:

#### Explanation:

A function can be thought of as a "rule" to follow to get an output. The most important thing about a function is that **for a set input, there is only one output**. This is what makes

(As a side note, this does not mean that one output cannot have multiple inputs. For example, if

The equation given in this question,

Additionally, this will hold for all values of x. There are no asymptotes, or imaginary parts of the graph. This means that the domain is all the real numbers of x, often written

The graph also has no maximum or minimum. The graph will extend to positive and negative infinity on the y axis; also think of this that any y value will give a corresponding x value. So the range is
