The graph of a function

Summary

• Given: a real-valued function of a real variable, \(f: A→B\) where \(A⊆R\) , \( B⊆R\)
• An ordered pair of two real numbers, denoted by \(\left( a,b \right)\) , can be represented by a point in a Cartesian coordinate system.
• The graph of the \(f\) is the collection of all ordered pairs \(\left( x,f\left( x \right) \right)\) where \(x\) is in the domain of \(f\) .
