Let A={x in R : |x+1| = |x|+1} and B ={x in R : |x-1| = |x|-1} , Then

The number of pairs (a,b) for which a(x+1)^2+b(x^(2)-3x-2)+x+1=0 AA x in R is :

A = {(x,y) : y = 1//x,0 ne x in R} , B = {(x, y) : y = - x, x in R} then

If f: A->B given by 3^(f(x))+2^(-x)=4 is a bijection, then A={x in R :-1

If A={x in R:x^(2)+6x-7 0} then which of the following is/ or correct 1)A nn B={x varepsilon R:-2

If f : R -> R is defined by f(x) = 1 /(2-cos3x) for each x in R then the range of f is

A question paper consist of questions, each carrying (1)/(2) mark, 1 mark and 2 marks ini the ratio 2:2:1. if the maximum mark in the exam is 100, then find the number of questions of each type.
