need help with algebra 2 !

[Togira Ikonoka]

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.

[Doubleshadow]

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.

[TurkishMonky]

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.

[Slater]

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
