f(x, y) = e¬aY sin(x + y) (г, у) —> (1, -1). as

Below are three functions with their domains and codomains specified. For each one, classify it as Injective but not surjective, Surjective but not injective, Neither injective nor surjective, or Bijective. If a function does have a property you do not have to explain why; but if a function fails to have a property, you should explain why in as specific of terms as possible. (Do not just state the definition of the property or give a vague reinterpretation of that definition, but refer to specific elements or other characteristics.) a.) f:Z→Z given by f(a)=a−1 b.)g:N→N given by g(a)=a2 c.) The mapping hh from the set of all lists of integers (such as [7,3,-2,10]) to Z that takes the list and returns the first element in the list. For example h([7,3,−2,10])=7

Determine if -Graph f:IR-R such that f(x) = x²+1 is surjective -Argue if it is a surjective

Give an example that: the f has an absolute minimum but not a local minimum.
