DOMAINPORTION OF X AXIS COVERED BY THE GRAPH
RANGEPORTION OF Y AXIS COVERED BY THE GRAPH
ROOTROOT OF F(X) ID THE ABSCISSA OF THE POINT WHERE GRAPH OF F(X) CUTS THE X AXIS
ASYMTOTELINE WHICH APPEARS TO BE TANGENT AT INFINITY
INCREASING FUNC.Y INCREASES WITH INC OF X
DECREASING FUNC.Y DECREAASES WITH INCREASE OF X
MAXIMA AND MINIMAMAXIMA AND MINIMA OF A FUNC ARE THE LARGEST AND SMALLEST VALUES OF A FUNCTION. EITHER within a given range - LOCAL MAXIMA/MINIMA OR in the entire domain - GLOBAL MAXIMA/ MINIMA
BOUNDED FUNCTIONIF we can draw two horizontal lines, alpha and beta such that the graph always lies between these two lines, then graph is called BOUNDED
least value of beta in bounded function is calledUPPER BOUND
MAXIMUM value of alpha in bounded func is calledlower bound
UNBOUNDED GRAPHSgraphs which are not bounded
SEMI Bounded graph typesonly upper bounded only lower bounded
EVEN FUNCTIONf(x)= f(-x) for all x belonging to domain graphs of even functions are SYMMETRICAL about y axis
ODD FUNCTIONf(x)= -f(x) for all x belonging to domain graphs of odd functions are SYMMETRICAL about origin, that is, opposite quadrants
PERIODIC FUNCTIONALL THE FEATURES are repeated after certain intervals
