a.

To determine

Whether the curve is the graph of a function of

Expert Solution

The curve of the graph is the function of

**Given information** :

**Concept used** : A curve in the coordinate plane is the graph of a function if and only if no vertical line intersects the curve more than once.

No vertical line intersects the curve of the graph more than once, hence the curves of the graph is the function of

b.
