Function-Exponent and logarithm

This post is about Exponential and Logarithm function . These function are inverse to each other.  Therefore graph function are reflection about line y = x . The questions are to change exponent to log and reverse. Exponential and Logarithm P P

Domain and Range of Function

Domain and range of functions are an important concept .  Domain  values define on x – axis  and Range is values on y- axis in the graph. Due to these values of functions, continuity of function defined. Another use of domain to show function defined. While range defined minimum and maximum value of function.   […]

Inverse and Composite function

Inverses and Composites  are two important concept of functions.  Composite function is defined as one function  defined inside another function. Like ff(x)) or f(g(x)) etc. Concept  of inverse is interchange of variables . Inverse notations are f-1(x),g-1(x) etc. Hence interchange is inverse. Therefore function and its inverse is reflection about y = x. Inverse and composite
