If i have 415 points and I give out 15 of them how many do i have left?

Easy 400 because u had 415 and gave away 15 so that would be 400 right? is this a trick question?

Step-by-step explanation:

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:  

[ 0 , ∞ ) , { y | y  ≥  0 }
