  8. 8. MODULE 3 RELATIONS AND FUNCTIONS Definition of terms A relation is any set of ordered pairs ( x,y), ( domain, range) Relation = {x/x is any ( x,y)} i.e., { (1,2), (2,3), ( 4,5), ( 6,7)}  A relation S is a function if and only if (a,b) S and ( a,c) S implies that b=c A function is a set of ordered pairs ( x,y) such that for each first component, there is at most one value of the second component.  A function is a set of ordered pairs having the property that no two distinct ordered pairs have the same first entry or domain. NOTE: All functions are relations but not all relations are functions. A graph represents a function if and only if no vertical line intersects the graph more than once. y 0 1 2 3 3 3

  12. 12. MODULE 4: POLYNOMIAL THEOREMS REMAINDER THEOREM If a polynomial f(x) is divided by (x-r) until a remainder independent of x is obtained then, the remainder is equal to P(r). FACTOR THEOREM If (x-r) is a factor of P(x), then r is a root of the equation P(x) =0. FUNDAMENTAL THEOREM OF ALGEBRA If P(x) is a polynomial with positive degree, then P(x) has at least one zero. THE NUMBER OF ROOTS THEOREM IF P(x) is a polynomial of degree n, then P(x) =0 will have n roots.  Descarte‟s rule of sign This states that for every change in the sign in a given polynomial this corresponds to the number of positive and negative roots. Example  FUNDAMENTAL THEOREM OF ALGEBRA Since the equation consist of a positive degree of n, therefore it has at least one zero.  THE NUMBER OF ROOTS THEOREM In the above equation the highest degree of exponent is 2, then there exist 2 roots of P(x)  Descarte‟s rule of sign  Consider the change in the sign of the first term and second term. last term. ( ) There are 2 positive roots taken from the original equation  FACTOR THEOREM ( )( ) ? ( ) ( ) 40-77+28=0 16-44+28=0 -28+28=0 -28+28=0 0=0 0=0 Then, 4 and 7 are the roots of

  17. 17. INTEGER PROBLEM Let x, x+1, x+2, x+3, x+4,… for a consecutive integer Let x,x+2, x+4, x+6, x+8,… for a consecutive even/ odd integer Age Problem Past & ago implies subtraction from the present age. Ex. A is one year younger than B means A‟s age is x-1 and B‟s age is x. In n th year means that one needs to add the particular number to the present age. In a given problem sentence, when one sees the word “is” this implies equal. Mixture The word” is/ must be added to “means add the two mixtures. The word “must be reduced to” means deduct the amount of mixture from the other. The word “to make a mixture of” or “to have a result of” means add up the two mixtures. Ex. A 5 gram of 20% SALT SOLUTION must be added to a pure concentration of SALT solution must be added to make a 75% Salt solution. 5g( 20%) + x g ( 100%) = 75%(5g + x g) WORK PROBLEM SAME JOB TO BE DONE X+Y = 1 RATE OF WORK= 1/X MOTION PROBLEM DISTANCE = RATE X TIME or d = rt
