A letter such as f, g or h is often used to stand for a function.The Function which squares a number and adds on a 3, can be written as f(x) = x 2 + 5.The same notion may also be used to show how a function affects particular values. Previous: Basic rules for exponentiation; Next: The exponential function; Similar pages. What is a function? It can be calculated using the formal definition, but most times it is much easier to use the standard rules and known derivatives to find the derivative of the function … A function is a rule that applies to a variable. Every function is a relation, but not all relations are functions. A functionis a rule that assigns a set of inputs to a set of outputs in such a way that each input has a unique output. 0000000016 00000 n Logarithm quotient rule For x>0, f (f -1 (x)) = e ln(x) = x.
