Domain of function f x. Finding the domain of a function cool math has free online cool math lessons cool math games and fun math activities. A function basically relates an input to an output there s an input a relationship and an output. This will be a list of x and y. Range is the set of value that corresponds to the domain.
Given a function composition latex f left g left x right right latex determine its domain. Find the domain of f. A function using the natural log ln. Misc 4 find the domain and the range of the real function f defined by.
Hence both its domain and range should be real numbers x can be a number greater 1 here f x is always positive minimum value of f x is 0. Find the domain and range f x x the domain of the expression is all real numbers except where the expression is undefined. If x is a real number x 2 is either positive or zero. Example 4 find the range of function f defined by.
