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....
A function is a relation where each x is paired with no more than one y. Note that the same y can be paired with different x's, but not the reverse. All linear equations, with the exception of vertical and horizontal lines, are functions. Is {(2,3),(4,1),(0,1),(2,−2),...
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: ...
a function is a special type of relation where: every element in the domain is included, and any input produces only one output (not this or that) an input and its matching output are together called an ordered pair so a function can also be seen as a set of ordered pairsMath...
A function is a relation in which each element of the set x corresponds to only one element of the set y. If the first element corresponds to two or more elements of the second, then it is not a function. Answer and Explanation:1 ...

Determine whether the relation is a function. {eq}\left \{ (-5, -4), (-2, 9), (-1, -2),(-1, 7) \right \} {/eq} Relations and Functions: A function can be imagined as a box that transforms an input to some output. Given some input {eq}k {/eq}, to this ...
( (-1,1)) , ( (0,0)) , ( (1,-1)) 相关知识点: 试题来源: 解析 Since there is one value of ( y) for every value of ( x) in ( (-1,1),(0,0),(1,-1)), this relation is a function. The relation is a function.反馈 收藏 ...
What is a quadratic function?Question:What is a quadratic function?function:A function is a relation between two sets which maps one element to one and only one element in another set. It is represented by {eq}f(x) {/eq} where {eq}x {/eq} is the independent variable.Answer...
