As it is a function and a parabola, it has many y-values. To find a certain one, you would plug a number in for x and solve it, or you could graph the equation see what points fall on the curve. In essence, that equation is the y-values.
the domain is all real numbers and the range is all real numbers the domain is all real numbers and the range is all real numbers
I am not entirely sure what the equation is supposed to be. However, to translate something 4 units up (4 units in the y-direction), simply replace every "y" in your equation by "y - 4". Simplify the result if you want.
It is (0, -2).

Probably g(x) = f(x) - 6 but it is difficult to be sure. Limitations of the browser used by Answers.com means that we cannot see most symbols.
