Answer» Mera 9th m 83% aaya h 10th m to saayd 80 > hi rhega bina tution Thanx bro .Maths m kaafi tej ho hm to weak hote jaa rhe bcoz dont have tution in my village ..Or town bhi ghr se 8km dur h beech m ghana jangal ? Question:To draw the graph of a quadratic polynomial and observe(i) the shape of the curve when the co-efficient of x square is positive and (ii) same when its negativeSolution:1 ) Draw a quadratic equation when co-efficient of x2\xa0is positive\xa0Lets our quadratic equation is y = x2 ( Here co-efficient of x2\xa0is +1 )Step 1 -\xa0find several points for equation y\xa0= x2 As:\txy = x2-39-24-11002439\tStep 2 -\xa0draw these points on graph and join them by smooth curving line As:2 )\xa0Draw a quadratic equation when co-efficient of\xa0x2\xa0is negative.Let our quardetic equation is As : y = -x2( Here co-efficient of x2\xa0is -1 )Step 1 -\xa0find several points for equation\xa0y\xa0= - x2\xa0As:\txy = -x2\xa0-3\xa0- 9\xa0-2\xa0- 4\xa0- 1\xa0- 1\xa00\xa00\xa01\xa01\xa02\xa04\xa03\xa09\xa04\xa016\tStep 2 -\xa0draw these points on graph and join them by smooth curving line As:
