Sign in to saverepresentation of a function as the set of pairs (x, f(x))
AI overview
A graph of a function is a visual picture made by plotting all the pairs of numbers (x, f(x)) where x is an input and f(x) is the output. It matters because seeing these points plotted helps you quickly understand how a function behaves—such as whether it's increasing or decreasing, where it reaches its highest or lowest points, and how the inputs relate to the outputs.
