​

Functions have only one input for each output (aka the x values never repeat)​

​Relation and Function

​

Multiple Choice

Mapping​s show the arrows from x to y values

​

If two arrows go from one x-value, it is not a function​

​

​Mapping

​

Multiple Choice

• relation

Multiple Choice

Is the following graph a function or not?

• not a function

• function

If you draw a vertical line through any place on the graph and it hits two points​, it is not a function

Multiple Choice

Determine the values of

a, b, and c for

the quadratic equation:

4x² – 8x = 3
