What is domain in algebra?
A domain is the x value or values of a set of points of a graph. do not repeat them. It should be written in the following fashion... d={enter x values here with commas between each} The concept of the domain of a function applies not just in algebra, but most areas of mathematics.
In mathematics how does one find a domain?
In mathematics, the domain of a function is the set of values that provide a real output. For example, for the equations y = 1/x or y - sqrt(x+3), the domain consists of all the values for x that provide a real output for y. For fractions, a denominator of zero will not provide a real output. For even roots, a negative value under the radicand will not provide a real output. One can find the domain by finding these exceptions and excluding them from the domain set.
What is range mean in mathematical terms?
Range is the difference between the high and low numbers in statistical mathematics. In coordinate mathematics it is the dependent or y of a (x,y) coordinate. * * * * * The range, in algebra, refers to the set of values that a function can take. Formally, it is the co-domain but few people (including mathematicians) use that term.
Why is the range the output and the domain the input?
A function may be defined over only certain values. That is, it may have only a certain set of values that can serve as input. For example, in elementary mathematics, the principal square root is only defined for non-negative real numbers. This is the "area" over which the function is valid and so it is called the domain. The mathematical term for the set of output values is actually the co-domain, but many people refer to it as the range.
Define a domain and co domain?
A domain is your Internet address. co is the latest domain introduction and is a good alternative if your .com domain is not available
