Is it a function or non function?

What?

Step-by-step explanation:

U need to add pictures for a question like this

Thanks :)

   
(vertical asymptotes)

as x approaches 0 from the left, the graph of f(x) increases without bound or  grows infinitely large in the positive direction.

as x approaches 0 from the left, the graph of f(x)  decreases without bound or grows infinitely large in the negative direction.



   

as x approaches 2 from the left and right, the graph of f(x) increases without bound or  grows infinitely large in the positive direction. so the limit evaluates to infinity.



   

as x gets larger and larger in positive direction, the graph seems to approach a constant value (horizontal asymptote) of 1.



   

the graph, as x gets larger in the negative direction, the graph oscillates around y=3. the oscillations get smaller and smaller; we can assume it approaches 3 as x gets larger in the negative direction.
