What you want to do is look our f of X term and plug.

On a graph, a solid dot is used for a closed endpoint and a hollow dot is used for an open endpoint.

f ◦ g is the composition function that has f composed with g. Be aware though, f ◦ g is not the same as g ◦ f. (This means that composition is not commutative).

0:00 5:15 Find F plus G F minus G F times G and F divided by G and the domain for the following two functionsMoreFind F plus G F minus G F times G and F divided by G and the domain for the following two functions f of X equals X minus 6 and G of X equals 5 x squared. Solution. So to find f plus g all you do is

The notation g ∘ f is read as "g of f ", "g after f ", "g circle f ", "g round f ", "g about f ", "g composed with f ", "g following f ", "f then g", or "g on f ", or "the composition of g and f ". Intuitively, composing functions is a chaining process in which the output of function f feeds the input of function g.

The open circle symbol ∘ is called the composition operator. We use this operator mainly when we wish to emphasize the relationship between the functions themselves without referring to any particular input value.

f ◦ g ◦ h is the composition that composes f with g with h. Since when we combine functions in composition to make a new function, sometimes we define a function to be the composition of two smaller function. For instance, h = f ◦ g (1) h is the function that is made from f composed with g.
