  WHAT ARE FUNCTIONS?   So in the previous post, we learnt about “ RELATIONS”. If you missed those posts kindly follow the link, as it is pre requisite knowledge to study functions. CLICK THIS LINK WHAT ARE RELATIONS?     Dear friends “ FUNCTIONS” are special type of “RELATIONS” In a Relation we associate elements of set “A” (DOMAIN) with the elements of set   “B”   ( CO DOMAIN) following a fixed rule. R = { (0,0), ( 1, -1) , (1, 1) , ( 4, -2) , ( 4, 2) , ( 9, -3) , ( 9, 3) } See how 1 associated with -1 and 1 in red colour. 4 with -2 and 2 in blue and 9 with -3 and 3 in green. R = { (0,0), (-1,1), (1,1), (-2,4) , ( 2,4), ( -3,9) , ( 3,9), ( -4,16), (4,16) } See how -1 and 1 are associated with 1 in yellow colour -2 and 2 with 4 in green ; -3 and 3 with 9 in red and -4 and 4 with 16 in black Now, we’ll take just one more example and then we can understand what functions are See how each -2 is connected with -1 only, -1 with 0 ...

Dear friends, As we all know, this year in class 10th maths exam (standard maths(041) and badic maths(241)), 4 questions based on case study will be there. Each question will have a word problem depicting a real life situation, on the basis of which there will be five parts. Students need to do any 4 parts for which they'll be awarded 4 marks. Many of the students are facing problems in such questions. To deal with such questions, Students require good understanding of the concept and also must have the habit and capability to apply the knowledge in different situations.  To practice such questions I am sharing a link with you. Just click on the link and download the pdf containing such questions. cbse class 10 mathematics case study questions Enjoy learning , stay blessed😃
