Q 2 & 3 . Topic Quadratic Equations . A level Mathematics

( 2 ) The function f is s.t f(x( )= atbeast for 04 x =20. It is given that f ( Ix ) = 5 bid f ( X )= 11. Find the set of the values of K for which the equation f(x ) =k has no solution (3) Points A and B Lie on the worve 4 = 2 2-ux +7. Point A has coordinates (4, 7 ) and B is the stationany point the curve. The equation of a line L is 4= mx-2, where m is constant. Find the set of valives of m for which L does not meet the curve bed by f: 2-262- 72- 5
