6. Using Lex-Order, (a) Find the next twelve 7-permutations on {1..9} after (8, 1, 3, 9, 7, 6, 4). (b) Find the next 7 full permutations on {1..12} after (8, 11, 10, 1, 12, 5, 3, 9, 7, 6, 4, 2).

Perform the required operations on the following functions given: f(x)= 3-x; g(x)= -2x find g[f(x)]

For each sentence below, find the value of x that makes each sentence true. (515) 5 = 25* x= (813)2 = 4* x=
