http://i.imgur.com/6Lt30z3.png
How would I know which are which is which
I factored it down like this
x^3 - 3x^2 - 40x
x(x-8)(x+5)
8,-5
I just can't seem to figure out which are right or wrong.

You can put this solution on YOUR website!
You factored the function correctly. You KNOW that the zeros are 0, 8, -5. Those are the same as the "roots" and "x-intercepts". Knowing the factorization and knowing (identifying) the roots of the function, you have no trouble finding which in the list of statements about H is true and which false.
