Intro Functions Review Sec 1, 2

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, typically written in the form (x, y).

Front

What is the range in a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0, 0).

Front

If I move up 2 units and left 3 units from point D, where do I end up?

Back

You end up at point K.

Front

What does the mapping {(0, 1), (1, 2), (2, 2), (3, 4)} represent?

Back

It represents a relation where each input (x-value) is paired with an output (y-value).

Front

What are the axes in a coordinate plane?

Back

The axes are the two perpendicular lines that define the coordinate plane: the x-axis (horizontal) and the y-axis (vertical).

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for a function.

Front

What is a quadrant in the coordinate plane?

Back

A quadrant is one of the four sections of the coordinate plane, divided by the x-axis and y-axis.

Front

How do you identify the coordinates of a point?

Back

Coordinates are identified as (x, y), where x is the horizontal position and y is the vertical position.
