ok so first factor out an x and tell me what the equation would look like

anonymous · Answer

x(x+12)

anonymous · Answer

good now if you notice that x is pretty much everywhere that means the domain is all real numbers

anonymous · Answer

let me show you what I came up with

anonymous · Answer

ok

anonymous · Answer

y=x(x+12) has x intercepts at (0,0) (-12,0)
domain all real  numbers
range real numbers >= -36

anonymous · Answer

actually that is correct

anonymous · Answer

ok. is that all the work I need to show?

anonymous · Answer

the easiest way to show the work is to show the graph

anonymous · Answer

ok I graphed it out also. file attached
