Quetion :- Using the definition of differentiation the derivative off - f ( ) = ( 3 / x ) and g ( x ) = (x 2 4 x+ 2 ) . Q soph (64) we know that the definition of differentiation f' ( x ) = lim f(ath ) - f (x) ho (if of ( x ) = 3 f (x) = lim f(ath ) - of ( x ) lim 3 W xth X =) lim xth lim 2 x ( ath ) lim 3 lim 3 3 h(oth ) x ( xx t xe) 2 2 Hence f' ( x ) = 3 2 2 similarly. J ( x ) = x2 4 x + 2 9' ( x ) = Rim grath ) - gra) (( seth ) - 4(x+()+2) -( 2124x+2) = = ) lim h lim P ( h+ 2 xe - 4 ) lim ( h+ 2 x - 4 ) = ( 2 21 - 4 ) Hence J'(x ) = ( 2 x - 4 ) And
