Surjective Injective Bijective Functions

SOLVED: decide whether it is injective, surjective, and/or bijective. If the function is a bijection, what is its inverse? If it is injective but not surjective, what is its inverse on the image of its domain?please check the question and answer clearly. I will thumbs up. Discrete math problem.my intuition tells me that it is injective but not surjective. If i am correct the inverse on the image of its domain can be identified based whether it is ≤ 0 or >0.
