Question

List the operations that can be performed on functions.

Accepted Answer

$$(f + g)(x) = f(x) + g(x)$$   
$$(f - g)(x) = f(x) - g(x)$$   
$$(fg)(x) = (f(x))(g(x))$$   
$$(\frac{f}{g})(x) = \frac{f(x)}{g(x)}$$   
$$(f \circ g)(x) = f(g(x))$$   
If $$(f \circ g)(x) = (g \circ f)(x)$$, the functions are inverses of each other.
