Determining a Relation as a Function

• Function
• Not a Function

All of the x values or inputs are called what?

• Domain

• Range

• Relation

• Function

A relation where each input has only one output.

• Domain

• Function

• Relation

• Solution

A function where every element of the range corresponds to exactly one element of the domain. Uses horizontal line test.

• slope-intercept form

• one-to-one

• y=mx+b

• range

A method of determining whether a graph represents a function or not.

• relation

• slope-intercept form

• inverse function

• vertical line test

The set of all possible input values of a function

• slope-intercept form

• Range

• Domain

• one-to-one

A function whose graph is represented by distinct and separate values.

• Continuous function

• Domain

• Discrete function

• One-to-one

The __________ is a visual method of determining whether a relation represented as a graph is a function by visualizing whether any vertical lines would intersect the graph of the relation at more than one point or not.

• Vertical Line Test

• Horizontal Line Test

• Angle Angle Side Test

• Parabola Test

A(n) __________ is a relation in which every input value is paired with exactly one output value.

• Relation

• Proportion

• Function

• Exponent

The __________ variable is the input of a function; a variable whose value determines the value of the output.

• Range

• Mapping Diagram

• Y-Axis

• Independent
