In the language of sets, a function f from the set Z to the set Y is the set of ordered pairs ( x , y ) defined by the relation yfx and is such that, if y ∈ Y exists for a given x ∈ X , then y is uniquely determined.doi:10.1016/B978-0-08-010782-0.50008-2K.S. SNELLJ.B. MORGANElementary Analysis

A relation is a set of ordered pairs. A function is a specific type of relation in which each domain value, or input, leads to exactly one range value, or output. Function notation is a shorthand method for relating the input to the output in the form y=f(x)y=f(x). In tabular ...

A relation is a set of ordered pairs. The set of first components is called the domain of the relation. The set of second components is called the range.doi:10.1016/B978-0-12-084750-1.50008-7Merlyn J. BehrDale G. JungstFundamentals of Elementary Mathematics...

Find five ordered pairs (x,y) for a graph with the equation y = 2x . Find the quadratic polynomial g(x) = ax^2 +bx + c which best fits the function f(x) = e^x at x = 0, in the sense that g(0) = f(0), and g'(0) = f'(0), and g''(0) = f''(0)...
