I don't know much about these two questions and would like the tutor to complete them by hand as required, preferably step by step

Q2. For the following functions f and g ,.. . Q3. Let C. be a positive real number. determine with reason whether Consider the following two functions ( fog ) ( x ) exists f : [ - 3 0 ) > R 2 { ( x ) = C - x ( i ) f: 1R - IR , f ( x ) = x " 4 and 9 : ( - 00 , 6 ] - 1R , g ( x ) = x + C . J : ( -0, 7] -> IR , 9 ( x ) = 1 7 - x Find all values of C. for which (ii ) f: ir -> IR , f( x ) = e and both ( fog ) ( x) and ( gof )( x ) exists 9: (0, 0 ) -> RR , g ( x ) = In ( x )
