it refers to a diagram or a model of a function; it shows that every input must generate one output. , The function represented in the graph is a one-to-one function. This means that every input must generate one output. The graph shows that there is a relationship between the inputs and outputs, but it does not show how the inputs are related to each other.

Every input must generate one output. This is what a function is. A function is a set of ordered pairs (x, y) where each input, x, corresponds to a unique output, y. A function can be represented by a graph on a coordinate plane. The graph of a function is the set of all points (x, y) in the coordinate plane that satisfy the equation y = f(x)
