Function
Posted by mathbro on August 23, 2008
A function is a rule which associates two or more than two variables. Functions can be understood with the help of a very simple basic example :
1. IF the distance (d) is constant, then the time taken (t) to cover that distance (d) will be dependent on the value of the speed (v). This can be written mathematically as t = f(v)
Normally any function is represented in the format of y = f(x)
