Inverses and Composite 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 […]

Inverse of function
Inverse of functions is an important concept . Domain values and Range values gets interchange . Due to these values of functions, continuity of function also change. Graph of inverse function also change and become y-axis oriented. Therefore graph of inverse is reflection of function graph about y = x. Inverse of Function
Rational and Reciprocal functions
A rational functions is a function of the form f(x)=p(x)/q(x), where p(x) and q(x) are polynomials and q(x)≠0 ,q(x)≠0 . The domain of a rational function consists of all the real numbers x=0 except those for which the denominator is x= 0 . reciprocal for a number x, denoted by 1/x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1.. The […]
Linear equation in two variable
Two variable linear equation. The general form of Linear Equations are ax + by = c, where a is not equal to 0. Solution of a Linear Equation gives one value of x. Because line intersect axes at one point. Linear Eq.
Linear equation in one variable
One variable linear equation. The general form of Linear Equations are ax +b= c, where a is not equal to 0. Solution of a Linear Equation gives one value of x. Because line intersect x-axis at one point. Two variable
