Hey ppl

Im struggling to answer some questions, abit embarsaing but im just getting so confused.

first question:

The Relation Q is defined by

q = {(x,y) E NxN :|x-y| < 2 } (please not < is less then or equal too kind find symbol)

Draw a arrow (mapping) digram that represents q?
Is q Reflexive or transitive? justify answer?


2)

Two functions are defined f(x) = 2x + 2, g(x) 1/2x-1; f, g R->R

Calculate fully y(x) = f(x)g(x)
and t(x) = g(g(x))

what is the relation between f(x) and g(x)

ii) Write down vertex degree for each graph>?


Finally

Construct a TM Macine that adds any two unary numbers. You are also advised ato 'run' some test strings on the TM you put forward.



Many thanks hope some gurus can help!!!
