Q1 [2 marks] You saw in the tutorials that an infinite set is c.e.iff it is the range of a 1:1 computable function. If we replace c.e. by computable, we can replace 1:1 by strictly increasing. In other words, an infinite set is computable iff it is the range of a strictly increasing computable function. Prove that statement. Recall: a function f is strictly increasing if x
