For the more general concept of the graph of a relation, see
relation. For another use of the term "graph" in mathematics, see
graph theory. For a graph-theoretic representation of a function from a set to the same set, see
functional graph.In mathematics, the graph of a
function f is the collection of all
ordered pairs (x,f(x)). In particular, graph means the graphical representation of this collection, in the form of a
curve or
surface, together with axes, etc. Graphing on a
Cartesian plane is sometimes referred to as curve sketching.The graph of the function is {(1,a), (2,d), (3,c)}.
