解析 Both a function and one to one functions are classified as a fundion.Aone-to-onme function however is a type of functin!If a relation passes the criteria nece ssary in order to he a function, it dees not necessarily mean it is also a one to one function. 反馈 收藏

it is a function. If not, then it’s not a function. Note that the vertical line test can’t tell you if you have a relation or a function though, because by definition all functions
What is a one-to-one function? Learn about one-to-one functions through graphs and examples and explore how to determine if a function is one-to-one. Related to this Question How to determine if a relation is a function. Determine whether the relation is a function. \{(-6, 3)...
In mathematics, what distinguishes a function from a relation is thateach xvalue in afunctionhas one and onlyONE y-value. Since relation #1 has ONLY ONE y value for each x value, this relation is afunction. On the other hand, relation #2 has TWO distinct y values'a'and'c'for the ...
由题干中关键信息“over-achievers and under-achievers”可定位至第一段第一句“There is a measurable relation between how much a person learns and that individual's attitude toward the subject to be learned”可知作者认为成绩优秀者和成绩较差者的差距在于对学习的态度,故选C。该句意为“一个人学习的...
There is a measurable relation between how much a person learns and his attitude toward the subject to be learned.When faced with a difficult learning task, one path to success is to concentrate on the positive aspects of the subject matter. If a student has a boring teacher, one solution ...
Afunctionis a type of equation or formula that has exactly one output (y) for every input (x). If you put a “2” into the equation x2, there’s only one output: 4. Some formulas, like x = y2, are not types of functions, because there are two possibilities for output (one po...
That is, each x has to have a UNIQUE corresponding y value. But look at what happens when I try to solve for "x=": My original function: f (x) = x2 + 1 First, I'll swap out the f (x) for the simpler y: y = x2 + 1 Now I try to solve for "x=": y −...
In a Database, Functional dependency performs assistance as a restriction between two sets of attributes. A Candidate Key in a relation is a minimal set of attributes of which can be used to identify a tuple distinctively. A candidate key is a column or set of columns in a table or relati...
