Suppose that the functions q and > are defined as follows. q (x) =3x-3 r(x)=x+5 Find the following. (g or) (3) = 0 (r . q) (3) = 0 XThe function a and I be defined by 2 (4 ) = 3 x- 3 how = k+5 - To find, ( qor ) ( 3 ) First we find, ( 201) ( x ) = 2 (r (x)) we know ( zor) ( x) = 2 ( r(x)) ] put The valueof rock from (iis ( zor ) ( 1) = 2 (xts ) - Here from (i, we know 21k) = 3x- 3 to find, 2 (x45), pw-(xts) on replace of k in (i) weget, 2 ( X+s ) = 3 (x+5 ) - 3 = 3x + 15- 3 = 3x+ 12 Now put The value cy 2 (x45) intill we get, ( 201 ) (1 ) = 3x + 12 Now put x = 3 we get, ( zor) (3) = 3 X3 + 12 = 9+12= 21 (Amwez ) To find ( roz ) (3 ) first we find ( rog)( 4) we know ( roz) ( 4)= (2(x) = r ( 2(4) ) put The valeof 214) from (ii) we get, (102) (14) = 1(2(")= 6(3x-3) Here from (il) we know rev= x+5, To find, r( 3x- 3 ) put 3 x- 3 ) on replace of x in (i) we get, So, r ( 3x -3 ) = ( 3X- 3) + 5 = 3x72 Now pul- r (3x - 3) = 3x+2 in Blov) we get ( no 2 ) ( x ) = 3 x +2 pat X = 3 we gee, ( boz ) ( 3) = 3x3+2 = 9+2 - 11 (Amwe )\f
