Mathematics in plain English - What is an ontology-function?

In mathematics, a surjective or a function in the area is equal to its value range. The range is set the target values, which is defined by y generated by the set of values ​​x for which function. formal function is, if for all y are in the range of values ​​of at least one x in the domain such that f (x) = y. In other words, this means that there isValue of the set of possible y values ​​that is defined in the function definition, not a value x in the interval. We continue this a bit '.

The functions are the correspondences between two or more defined variables. The most common is a function defined between the two variables x and y such that y = f (x), as in the linear function y = 5x + 2 rangeDefine a function x is the set of values ​​x for which the function is defined and the range is all y values ​​generated by these values ​​In general, these sets of values ​​is not explicitly specified. In these cases, the domain is thought to be eligible for all values ​​x, and the range of y-values, which is usually obtained as a result of substitution of these values ​​in xspecified by the function. In that provision, the function y = 5x + 2

What I value my time allowable x in the previous paragraph is simply that the values ​​of the function, this in itself is defined: that is, we exclude the values ​​of x, which leads to meaningless phrases, such as zero, obtained by dividing, or negative square roots. This domain may be emergency situations all x values. AsFunctions are usually defined at the beginning of the set of real numbers, domain name, such as a linear function, where would all the real numbers. Since for a given value of yy-value, we find that a value x product, the area is all real numbers. 5 to obtain xx = (y - / 2) you can see better through the solution.

To see this time domain, on the situation a bit 'moreclearly, we use the function above and examine its graph. Since this is a straight line, the curve continues indefinitely in both directions. We can draw an infinite number of vertical lines along the curve, and will cut off all points in the horizontal or x-axis. Thus, the domain of all real numbers. We can do the same thing with an infinite number of horizontal lines and that all points in the vertical or y-axis intersect. Since the function defined on all real numbers andArea is equal to all real numbers, this feature is active. In fact, linear functions are all on. What's more, they are also one-on-one.
