Sorry, I'm no help because I have no idea how to do those!
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: ( − ∞ , ∞ ) , { x | x ∈ R }
Range: ( − ∞ , 16 ] , { y | y ≤ 16 }
Even numbers are divided by two
Even numbers are easier to cope with in math problems
There are only odd prime numbers
There's a site called m.a.t.h.w.a.y, and you can type in those functions in order to get the graph ;)
