Defining Functions from Patterns

A relation where every input in matches with exactly one output is called what?

• Relation

• Linear

• Exponential

• Function

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.

What type of function is shown?

• absolute value

• quadratic

• linear

• exponential

This mapping is.....

• a function, because Feb has two outputs, 28 and 29

• a function, because two inputs, Jan and Mar, result in the output 31

• not a function, because Feb has two outputs, 28 and 29

• not a function, because two inputs, Jan and Mar, result in the output 31
