can anybody give some help with my math i need help with quadratics and graphing in algebra 2 mainly how do u find the range of an equation and anything else that might help me in this subject.

Range of an equation is what y values the graph has. I usually just reason it out by looking at the graph. For example:

y = x + 1 The graph extends infinitely in both vertical (and in this case, horizontal) directions, so its range is from negative to positive infinity. (-Â¥ ,Â¥ )
y = X^2 (x squared) Here, the graph is from 0 to positive infinity, and includes zero. [0,Â¥ ) Note the bracket versus the parentheses.

Typically, if the range is limited, it will be from a given number to one of the infinities.
y = x^2 + 6 Here, the range is from [6, ¥ ). The y-intercept is the vertex of the graph, and very obviously its lowest point.

Did that help and any other specific questions?

hey on a totally unrelated question, how many megabytes per gigabyte.

1024 or 1000, depending on who you ask...

No. The people who say a thousand flat are wrong. It's 1024. When you put the "byte" in there, it means you're using the base 2 numbering system, not the base ten.

I'm totally pedantic on these points.

right. There are NEVER 1000 MB per GB. When thinking of computers, think in powers of 2, not 10. There are 2^3 bits in a byte, 2^10 bytes in a KB, 2^10 KB in a MB, 2^10 KB in a MB, 2^10 MB in a GB, 2^10 GB in a TB, 2^10 TB in a PB, 2^10 PB in an EB, etc etc etc. Chances are that unless you're working in a special lab, you won't see a PB for another 8 or 10 years, and if you ever see an EB, chances are that you're working on Win95 and have come across a glitch.

As for finding the range... that's something done easiest using basic calculus. However, for now, you can think of the range as being how high and how low a function can go, and the domain is how far left and right the function can go.

well yes, but turkishmonkey was right on that it does depend who you ask . If you're looking at information on a box or sales material (aka from a marketing person) there is a strong chance it is 1000. But technically (and correctly) it is 1024
