TN 11th, Maths Chapter 1, Exercise 1.3

Image
  Welcome To Class : XI Subject : Maths Chapter : 1 Exercise : 1.3 Que 1 : Suppose that 120 students are studying in 4 sections of eleventh standard in a school. Let A denote the set of students and B denote the set of the sections. Define a relation from A to B as “x related toy if the student x belongs to the section y”. Is this relation a function? What can you say about the inverse relation? Explain your answer. Solution :   A = {set of students in 11th standard} B = {set of sections in 11th standard} R : A ➝ B ⇒ x related to y ⇒ Every students in eleventh Standard must in one section of the eleventh standard. ⇒ It is a function. Inverse relation cannot be a function since every section of eleventh standard cannot be related to one student in eleventh standard. Que 2 : Write the values of f at – 4, 1, -2, 7, 0 if Solution : f(-4) = -(-4) + 4         = 4+4         = 8 f(1) = 1 – 1²         = 0 f(-2) = (-2)² ...
