For a set of points to be a function each x can only be paired with one y value.

. A relation that is a function. So this relation is a function. In the second set of points the x point 2 has two different y values so this is not a function.

1 on a question Which of the following relations represents a function. This is also called one-to-one mapping illustrated as follows. A 8 c 14 b - 10 d - 4 3.

The function that describes the height The greenhouse effect is the result of ______ that becomes trapped by Earths atmosphere causing Earth to be much warmer Categories. Here domain 258111417 and range 1 ii 21426384105126147 It is a function as every input has a single output. So 2581114 and 17 are the elements of the domain of the given relation.

Express the following relations as a mapping state the domain and range then determine if is a function. F x 2x FR Rf x x. Hence this relation is not a function.

We say the output is a function of the input We say the output is a function of the input The input values make up the domain and the output values make up the range. Let us look at some examples to understand how to determine whether a relation is a function or not. Ii For each x A there is only one y B such that x y f.

So for a quick summary if you see any duplicates or repetitions in the x-values the relation is not a function. -1 5 0 3 2 3 3 -1 Yes it is a function. This relation is definitely a function because every x-value is unique and is associated with only one value of y.

Determine if the Relation is a Function 12 23 34 45 56 Since there is one value of for every value of in this relation is a function. Is the relation a function in figure 4. Given the above graph as in.

Ii 33211223 2 is repeating. If it is a function determine its domain and range. - A function is always a relation.

Given gx-3x² 2 the value of g-2 is equal to. Let A 1 2 3. The number of hours Claire expect to be gone D.

A c 4 2 b -4 d 2 4. OfRR f x 10 X OfR R x x2 Which of the. Yes because the x-value 11 has two y.

1 3 2 3 1 4 b. Here domain 2 5 8 11 14 17 and range 1. In the third set of points the x value 0 had two y values so this is not a function.

Check whether the following relation is a function. Finding Domain and Range Domain Set of first elements in the pair of the function 2 5 8 11 14. In algebra a function is a relation in which each input x only gives one output y.

24 14 15 b s- 21 - 12 12 21 34. 2 2 2 3. In the first set of points each x value only has one y value so this is a function.

2 3 1 3 3 3 c. Which of the following relations is a function from A to A. Which of the following relations is a function from A to A.

- A relation is a function if and only if the x- values do not repeat in a given set. A function is a relation in which each possible input value leads to exactly one output value. Solution for Which of the following relation is a function.

If a relation is a function it has to satisfy the following conditions. NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS. Computer Science questions and answers.

B 1 5 1 5 3 -8 3 -8 3 -8 Though a relation is not classified as a function if there is a repetition of x values this problem is a bit tricky because x values are repeated with their corresponding y-values. Iii 12223242 All these 1234 are non-repeating. Given the graph of Sx on the right the value of 2-f-4 is equal to.

Does the following relation represent a function. The relation is a function. Which of the following relations represents a function.

Which of the following relations is not a function. I 2 1 5 1 8 1 11 1 14 1 17 1 Since 2 5 8 11 14 and 17 are the elements of the domain of the given relation having their unique images this relation is a function. It is a function as every input has a single output.

Hence this relation is not a function. Hence they have unique image. In the fourth set of points the x value 1 has two.
