Assessment #9: Coordinate Plane, Domain, Range, Functions

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (x, y).

Front

What are the four quadrants of the coordinate plane?

Back

1st Quadrant: (+, +), 2nd Quadrant: (-, +), 3rd Quadrant: (-, -), 4th Quadrant: (+, -).

Front

What is the definition of domain in a function?

Back

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

Front

What is the definition of range in a function?

Back

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

Front

How can you determine if a graph represents a function?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

Front

What does it mean for a relation to be a function?

Back

Each input (x-value) must correspond to exactly one output (y-value).

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point on the coordinate plane.

Front

What is the significance of the x-axis?

Back

The horizontal line in the coordinate plane where y = 0.

Front

What is the significance of the y-axis?

Back

The vertical line in the coordinate plane where x = 0.

Front

What is the point of origin in the coordinate plane?

Back

The point (0, 0) where the x-axis and y-axis intersect.
