1. 2.2 The Graph of a Function Should I give up, or should I just keep chasing pavement, even if it leads nowhere? -Adele

2. Vertical Line Test A set of points in the xy -plane is the graph of a function if and only if a vertical line intersects the graph in at most one point.

3. A Function’s Graph Find the following information about the function: 1) Is the point (-1,1) on the graph? What about (1,3)? 2) If x = 3, what is f (x) ? What is the point on the graph of f ?

4. A Function’s Graph Find the following information about the function: 3) If, what is x ? What is/are the point(s) on the graph of f ? 4) What is the domain of f ?
