A function relates an input to an output. It is like a machine that has an input and an output. And the output is related somehow to the input.
这种关系是一个函数?which relation is a function?A:(0,1),(0,2),(2,3),(3,2)}B:{(2,4),(3,5),(4,6),(5,6)}C:{(3,1),(1,3),(2,1),(2,3)}D:{(5,2),(5,3),(2,2),(3.3)}1.We are thinking about the x and y values in a coordinate grid.2.Another ...
A function in mathematics is a relationship between two variables, usually denoted {eq}y {/eq} and {eq}x {/eq}, where {eq}x {/eq} is considered an input, or independent variable, and {eq}y {/eq} is the output, or dependent variable. A function is a special type of relation ...

Function: A function is a relation where everyx-value is unique. So, the relation(1,3),(2,5),(3,11)is a function as nox-value is repeated. Meanwhile, the relationy=±xis not a function it contains the points(1,1)and(1,−1), so there are repeatedx-values....
If the relation is a function, state its codomain an d range.$$ A = \left\{ 1 , 2 , 3 \right\} , B = \left\{ 3 , 4 , 5 , 6 \right\} , a n d g = \left\{ ( 1 , 5 ) , ( 2 , 4 ) , ( 3 , 3 ) \right\} $$ 相关知识点: ...
Answer to: Determine if the given relation is a function: {(-7 , 0), (4 , 2), (4 , 1), (-2 , 3), (6 , 0)} By signing up, you'll get thousands of...
Which relation is a function? ( ) A. \( (1,1),(2,2),(3,3),(4,4),(5,5)\) B. \( (1,1),(1,2),(1,3),(1,7),(1,9)\) C. \( (1,4),(3,4),(3,4),(4,4),(5,4)\) D. \( (1,1),(2,2),(1,3),(2,4),(5,5)\) 相关知识点: ...
一楼请不要答非所问 这个是个function，because according to the definition of a function each value of x can only have one corresponding vaule of y..在题目中每个x value只有一个y vaule ，所以这个是function determine
