Let N be the set of all positive integers, 1, 2, 3, define two functions / and g from N
Chapter 2, Problem 107(choose chapter or problem)
Let N be the set of all positive integers, 1, 2, 3, define two functions / and g from N to N:.We/ (jc) = 2jc, for all jc in N fjc/2 if jc is even ^(jc + 1)/2 ifjcisodd g(x)Find formulas for the composite functions g (/(*)) and / (#(jc)) . Is one of them the identity transformation from N to N? Are the functions / and g invertible?
