I've got you covered. It depends on what kind of equation you are transforming. Line? Circle? Ellipse? Parabola? Hyperbola?

y=(x+1)2 and behind the last parenthesis is suppost to be to the 3rd power

That's a Line. so, the slope is made negative by the minus 1 before the parentheses. The term in the parentheses is x1, so you have x   1 to give you x+1 there so you shift to the left by 1. That's the key. Remember that term is always xd, so if you see a plus remember it's really d. The 2 shifts horizontally downward by 2.

Oh, wait a minute. I didn't see your cube. are you sure that's not a second power?

A SECOND POWER on that term makes it a parabola.

And where I said slope is negative, what you have then is a parabola opening downward.

And the thing that minus 1 before the parantheses does is reflect it across the x axis to make it point downward. Do you see that?

yes it just confused me because i dont understand how should i know when to flip it over the yaxis or xaxis.

Where you see the X reflection is the term outside the parentheses. Where you see the Y reflection is the sign of the first guy in the parentheses. f(x) = a(xh)^2 +k + or minus on the a term is reflection across the xaxis. + or  on the x term is reflection across the yaxis. the sign of h is the shift left () to right (+), IMPORTANTLY remember the minus in xh is always there regardless of what the sign hidden in h is. (x+h) is really [x(h)]. (xh) is really [x(+h)]. and the sign on the k term drives the vertical shift (+ is up,  is down).

If you have a graphing calculator, or can download Microsoft Math (free), or can go to the wolfram site, you should experiment with entering an equation and changing each value to see what happens. That's how I learned it. You can test your thinking that way, too.
