WebAnswer: We consider y=f(x) a function when there is a unique y-value for all x in the domain. If f(1)=10 and f(1)=2 then that violates the criterion that there is a unique y-value for a specified x=1. This violation comes about when we solve y^2=x and get 2 branches, y=sqrt(x) and y=-sqrt(x). Th... WebIf you mean can it have the same y-value for two different x-values, then yes. Consider y = x^2. When x is either - 1 or 1, y is 1. When x is either - 3 or 3, y is 9. y = x^2 is a …

WebIf your function has three variables, view the domain as a set of ordered triplets. Then you might imagine points in space as being the domain. Once you get more than 3 variables the idea is the same. So for a 5-variable function the members of the domain are ordered 5-tuples and look like this: [x1, x2, x3, x4, x5] It just becomes harder to ... Web• Let X and Y be two discrete random variables defined on the same experiment. They are completely specified by their joint pmf pX,Y (x,y) = P{X = x,Y = y} for all x ∈ X, y ∈ Y • Clearly, pX,Y (x,y) ≥ 0, and P x∈X P y∈Y pX,Y (x,y) = 1 • Notation: We use (X,Y) ∼ pX,Y (x,y) to mean that the two discrete r.v.s have the ...
WebFeb 13, 2015 · By definition, f(x) is a manipulation on the number x such that we get another number, y. Since any function must be clearly defined, when we input a value of x we should get a unique number, not a set of numbers. Therefore, one value of x must only … WebAug 19, 2024 · Defining a function once allows you to use this function within other functions. You can combine multiple functions together to create a separate function …
WebA function rule is an equation that describes a function, and it may use the function notation f (x). In an inverse function, the x-values (domain) and y-values (range) are switched. A linear function produces the graph of a straight line, which you can make from a table of values or from a linear-function rule.
