Differential Calculus
A surjective function, also known as an onto function, is a type of function where every element in the codomain has at least one element from the domain mapping to it. This means that the range of the function is equal to its codomain, ensuring that no output value is left out. Understanding this concept helps in recognizing how functions can map inputs to all possible outputs and is essential for exploring more complex mathematical ideas like inverses and function composition.
