Functions

What is a function?

•  a relation between a set of inputs and a set of permissible outputs with the property that each input (x) is related to exactly one output (y). 
• Set of all x values
• Set of all  y values
• Vertical line test

Is this a function? Explain.

• Yes; it passes the horizontal line test.
• No; it is not a straight line.
• Yes; it passes the vertical line test.
• No; there is a line connecting the dots.
