WebA function is a relation from a non-empty set B such that the domain of a function is A and no two distinct ordered pairs in f have the same first element. A function from A → B and (a,b) ∈ f, then f (a) = b, where 'b' is the image of 'a' under 'f' … WebFunctions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited. Sort by:
