given f(x) = x^3 - 6x^2 + 9x and g(x) = 4
1) find the coordinates of the points common to the graphs of f and g
2) find all the zeros of f
3) If the domain of f is limited to the close interval [0,2], what is the range of f?

Pleas Help, thx in advance

Hi, I'm an Aussie moving to Canada soon and have always been facinated by Wolverines (not to the point where I want to be bitten by one!!). So they're not a bear and they're not a badger that much is true. Has anyone had any experience of them? What are they like? Characterwise. Thanks

If I look a pen and then cover my eyes with my hands, I will not see the pen. Similarly if I look at a star and for some unknown reason some dark matter happen to come in between me and the star what will I see?

can you guys give me the steps to solve these questions? my first question is :

given points A(-3, 2), B(6,8), and C(-4,6), determine the coordinates of a point D on the y axis so that CD is parallel to AB.

i dont really know what to do after finding the slope?

and this other question i dont get.

Find the value of k if the slope of kx-3y= -9 is 1/9

thanks loots
