Question

select all descriptions that accurately define the meaning of a function. every y - coordinate has one unique x - coordinate. every dependent variable has one unique independent variable. every x - coordinate has one unique y - coordinate. set of ordered pairs. every independent variable has one unique dependent variable.

Explanation:

A function is defined such that each input (independent variable/x-coordinate) maps to exactly one output (dependent variable/y-coordinate). A set of ordered pairs can represent a function only if it follows this rule, but the set alone does not define a function. The incorrect options reverse the input-output mapping requirement.

Answer:

• Orange: Every x-coordinate has one unique y-coordinate.
• Blue: Every independent variable has one unique dependent variable.
