5. I don't think it should matter. Perhaps your teacher might have some requirement. The answers are -4 and 6. These are both domain values for the function. When expressing domain and range values in a function, the x and y values are shown as (x,y) indicating (domain, range). So maybe you could express these as (-4,0) and (6,0). Maybe someone else can comment here about this.
