Finding domain of a function practice
WebA special type of relation, called a function, occurs extensively in mathematics. A function is a relation that assigns to each element in its domain exactly one element in the range. For each ordered pair in the relation, each x -value is matched with only one y -value. WebIt is important to know when we can apply a composite function and when we cannot, that is, to know the domain of a function such as f ∘g f ∘ g. Let us assume we know the domains of the functions f f and g g separately. If we write the composite function for an input x x as f (g(x)) f ( g ( x)), we can see right away that x x must be a ...
