Vocabulary Practice

What is a relation?

• Pairs a set of inputs with a set of outputs.

• To pair an input (or a point) to an output (or another point).

• one input maps to many outputs.

• A graph that is not a straight line.

What is an output?

• The variable of a relation, often denoted by x in an ordered pair (x, y).

• A diagram used to represent a relation, showing a set of inputs paired with a set of outputs.

• The dependent variable of a relation, often denoted by y in an ordered pair (x, y).

• To pair an input (or a point) to an output (or another point).

What is a one-to-one relation?

• A relation in which one input maps to many outputs.

• A relation in which many inputs map to the same output.

• A relation in which many inputs map to the same output.

• A relation in which one input maps to one output.

What does it mean to map?

• A test to determine if a graph represents a function.

• To pair an input (or a point) to an output (or another point).

• To assign the image of each point on a plane under a transformation.

• A diagram used to represent a relation, showing a set of inputs paired with a set of outputs.

What is a one-to-many relation?

• Describes a relation in which one input maps to many outputs.

• Describes a relation in which one output maps to many inputs.

• Describes a relation in which many inputs map to the same output.

• Describes a relation with the properties of a one-to-many relation and a many-to-one relation: one input maps to many outputs, and many inputs map to the same output.

What is a vertical line test?

• A function that maps a point to another point on a plane.

• A transformation that moves a point across a fixed line of reflection. The image is the mirror image of the original figure with the line of reflection as the mirror.

• A test to determine if a graph represents a function.

• If a vertical line intersects the graph at more than one point it is a nonlinear function.

What is an input?

• The variable of a relation, often denoted by x in an ordered pair (x, y).

• To pair an input (or a point) to an output (or another point).

• The dependent variable of a relation, often denoted by y in an ordered pair (x, y).

• Describes a relation in which one input maps to many outputs.

What is a mapping diagram? Select all that apply.

• To assign the image of each point on a plane under a transformation.

• To pair an input (or a point) to an output (or another point).

• When you map one output to one output in specific.

• A diagram used to represent a relation, showing a set of inputs paired with a set of outputs.

What is a function? Select all that apply.

• A type of relation in which each input maps to only one output.

• A graph that is not a straight line.

• A relation that does not have a constant rate of change. A nonlinear function cannot be represented by a linear equation y = mx + b.

• One-to-one relations and many-to-one relations are functions.

What is a curve?

• A graph that is a straight line.

• A graph that is not a straight line.

• A function that has a constant rate of change.

• A graph known as a curve can be represented by the linear equation y = mx + b.
