Question

What is the most compact mathematical representation of a function? A) Equation B) Domain C) Graph D) Data table

Answer 1

A) Equation

Explanation:

Compared to an equation (ex.
`y=mx+b`) and the domain (ex. ℝ) of a function, a large graph or data table with multiple rows cannot be considered compact, so eliminate C) and D). Although the domain may seem more compact than an equation, it does not completely represent a function like an equation, so eliminate B). The answer is A) Equation.
