function 称为函数 也就是 f(x) 中的 f domian 称为定义域 也就是 f（x） 中的x的范围 range 称为值域 也就是 f(x)整体的范围 Domain（定义域）域 是一组具有相同数据类型的值的集合，又称值域。 Domain例如：整数、实数和字符集合都是域。域中所包含的值的个数称作域的基数。在关系中，...
Find the domain of function ff defined by: f(x)=√−x+2(x+1)(x+9)f(x)=−x+2(x+1)(x+9) Example 4Find the range of function ff defined by: f(x)=x2−2f(x)=x2−2 Solution to Example 4The domain of this function is the set of all real numbers. The range is ...
This article will explain the domain and range of a function mean and how to calculate the two quantities. Before getting into the topic of domain and range,
What are the domain and range of the function? ( ) A. Domain: (-∞ ,∞ ); Range: (-∞,∞) B. Domain: [-2,∞ ); Range: (-∞ ,∞ ) C. Domain: (-∞ ,∞ ); Range: [-2,∞ ) D. Domain: (-∞ ,∞ ); Range: [1,∞ )...
Definition: Domain and Range of a Function The domain of a function is the set of all input values of the function. The range of a function is the set of all possible outputs of the function, given its domain. The domain tells us all of the inputs “allowed” for the function. For...
