Coordinate Plane, Domain, Range, Functions Review Before Flashcard

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

How do you determine if a relation is a function?

Back

A relation is a function if each input (x-value) corresponds to exactly one output (y-value).

Front

What does an ordered pair represent?

Back

An ordered pair represents a specific point on the coordinate plane, defined by its x-coordinate and y-coordinate.

Front

What is the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair, indicating the horizontal position on the coordinate plane.

Front

What is the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair, indicating the vertical position on the coordinate plane.

Front

What is the significance of the point (0,0) on the coordinate plane?

Back

The point (0,0) is known as the origin, where the x-axis and y-axis intersect.

Front

What does it mean for a point to be on the x-axis?

Back

A point is on the x-axis if its y-coordinate is 0, meaning it lies horizontally along the x-axis.

Front

What does it mean for a point to be on the y-axis?

Back

A point is on the y-axis if its x-coordinate is 0, meaning it lies vertically along the y-axis.
