Determine which of the following functions are injective, surjective, bijective (bijectivejust means both injective and surjective). And Find a left inverse for f or explain why none exists.Find a right inverse for f or explain why none exists. (a)f:Z−→Z, f(n) =n2. (d)f:R−→R, f(x) = 3x+ 1. (e)f:Z−→Z, f(x) = 3x+ 1.

We know that real-world markets are neither perfectly competitive nor purely monopolistic. Changes in market conditions occur as a result of innovations and technological changes, regulatory changes, and resource availability on the production (supply) side, on the one hand, and changes in consumers' preferences and incomes on the demand side, on the other hand. As a result, over time, some industries become more competitive and some become less competitive or more monopolistic. In your view, in recent years which industries...
