Okay, so I expanded the brackets and simplified the equation from (x+4)(x-4)(x-4) to equal
x3-4x2-16x+64 and I needed to sub those values into this equation y=ax3+bx2+cx-d where a=x3 b=-4x2 c=-16 d=64 which were the values I got from the first equation. I need confirmation If it would be y=x6[/SUP]-4x4-16x2-64
I dunno, it just doesn't seem right.
