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 … WebA function is a special kind of relation. In a function, there can only be one x-value for each y-value. There can be duplicate y-values but not duplicate x-values in a function. …

WebA function can have repeating y values, and a single y value can repeat two or more times. In fact, a y value can repeat infinitely many times for a function. However, a function with repeating y values is not one-to … WebExamples. The function () = is an antiderivative of () =, since the derivative of is , and since the derivative of a constant is zero, will have an infinite number of antiderivatives, such as , +,, etc.Thus, all the antiderivatives of can be obtained by changing the value of c in () = +, where c is an arbitrary constant known as the constant of integration. ... WebThis means give x a value and y will be double of x e.g. if x = 2, y = 2 × 2 = 4. A function is just a different way of expressing this. Instead of y, we write f (x) which is read f of x (please verify) So y =2x becomes f (x) = 2x. Input x and get output f (x) which basically says multiply x by 2. 1 comment. shangrilanyc twitter

"WebThink of a parabola, such as y=x 2. One y value will always have a pair of x values that arrive to that y value (in this case, symmetrically about x=0). A parabolic equation is a function; specifically y is a function of x when y=x 2, but x is not a function of y, because you do not get a specific value of x with any given y value.

WebJan 27, 2024 · A function must have every domain value associate to only one y-value. Ok, that makes sense. But then, in a function, one y-value IS able to map to 2 different domains. Why? This puzzles my logic. A function has a rule, so if, per say, my rule is f(x)=x+1 , then I can have the following set: {(1,2),(2,3)}. WebOct 24, 2024 · Can 2 different functions have the same domain and range? Hence, every given domain value has one and only one range value as a result, but not necessarily vice versa. In other words, two different values of x can have the same y -value, but each y -value must be joined with a distinct x -value.

Webf (x) = x 2 + 4x + 4. f (x) = -1/2 x + 2. f (x) = x 3 + 1. Horizontal lines are also linear functions, although they do not have an x-value. A horizontal line comes from any equation like y = 3 or y = 6. The line crosses the y-axis at the number given and is horizontal; for any value of x, the y-value is always the same. WebJun 24, 2024 · A y-intercept is a point where the x-value is 0. x=0 is not part of the domain of any of these functions, so there are no y-intercepts. The maximum values of these functions are ... f(x): 1; g(x): -4; h(x): 2; so h(x) has the greatest maximum value. The range of each function is the list of its table values. No two functions have the same range ...

WebJust like a relation, a function is also a set of ordered pairs; however, every x x -value must be associated to only one y y -value. Suppose we have two relations written in tables, A relation that is not a function. Since we have repetitions or duplicates of x x -values with different y y -values, then this relation ceases to be a function. WebOk, so basically, he is using people and their heights to represent functions and relationships. 1 person has his/her height. He/her could be the same height as someone else, but could never be 2 heights as once. This goes for the x-y values. An x value can have the same y-value correspond to it as another x value, but can never equal 2 y ...

WebJul 7, 2024 · In answering these, remember that by definition, a function can only have one output (y-value) for each input (x-value). A function having more than one y-intercept would violate this, since it would mean that there are two outputs for x=0. Therefore, it is not possible for a function to have more than one y-intercept.

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.
