A (a)   is a mathematical relation that maps a set of input values to a set of output values such that each input value is mapped to exactly one output value. The set of input values of a function is called the (b)   , represented by the (c)   variable. The set of output values of a function is called the ​ (d)   , represented by the ​ (e)   variable.​ ​ ​
