Ex 23 1 Which of the following relations are functions.

Which of the following relations is a function. A function is a correspondence between two sets called the domain and the range such that to each element of the domain there is assigned exactly one element of the range. F a t f b s f c. Which of the following relations is not a function.

X is a real number Range. BIt is NOT a function because there are multiple y-values paired with a single x-value. If fx is a function defined xR and fxfx0x 2T 2T and has period T then ϕx ax ftdt is also periodic with period T.

Also the element 1 of the domain set has two images 2 and 3 of the range set in the relation g 1 2 1 3 3 1 So g is not a function. 37 38 3-2 34 31 AIt is a function because the order pairs all have the same x-value. If a b and a c belong to r then b c.

Domain Set of first. Which of the following relations is a functionA. 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.

X is a real number Range. Which of the following functions has an inverse that is not a function. In algebra a function is a relation in which each input x only gives one output y.

G 32 21 82 57 h 41 23 2 6 7 2 y 29 34 92 67. A function will have different x values in each ordered pair. 0 2 4 6 and has exactly one output for each element.

A function from A to B is a relation on the product of A and B which I will represent by AXB. Here domain 2 5 8 11 14 17 and range 1. You could set up the relation as a table of ordered pairs.

Y 4. All these are not repeating. I Domain of f is A.

So this relation is a function. Which of the following relations isare functions. Y 4 B.

B s t u defined as follows. Then test to see if each element in the domain is matched with exactly one element in the range. F and h are relations from A B where A a b c d.

Watch this tutorial to see how you can determine if a relation is a function. X 12 34 17 51. So for a quick summary if you see any duplicates or repetitions in the x-values the relation is not a function.

Which of the following gives the correct domain and range for the relation graphed. How do you figure out if a relation is a function. If a relation is a function it has to satisfy the following conditions.

As each element of the domain set has unique image in the relation f 1 3 2 3 3 2 So f is a function. 2 1 5 1 8 1 11 1 14 1 17 1 The first elements are 2 5 8 11 14 and 17. But for relation r to be a function it must satisfy two criteria.

A relation that is a function. 2 Get Another question on Math. A function is a special type of relation where every input has a unique output.

This relation is definitely a function because every x-value is unique and is associated with only one value of y. 26 Which of the following type of relations could be a function A One to many B from GMATH 2621 at Saint Louis University Baguio City Main Campus - Bonifacio St Baguio City. So according definition of function given relations with domain A 0 2 4 6 a 6 3 2 1 0 3 4 5 0 3 2 1 4 5 6 3 is function since it defines for every element of function i.

B 1 5 1 5 3 -8 3 -8 3 -8 Solution. Ii For each x A there is only one y B such that x y f. Let us look at some examples to understand how to determine whether a relation is a function or not.

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. The relation is a function. 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.

Hence they have unique images. Which of the following relations is a function. If it is a function determine its domain and range.

There are 3 flowers in vase a and 2 flowers in vase b 6 more flowers are added to vase a how many flowers must be added to vase b so that the ratio of the number of flowers in vase a to the number of flowers in vase b remains the. All real numbers DDomainO. Check whether the following relation is a function.

If so you have a function. So A is not a function because of the 1s in 12 and 13 B is a function. Does the following relation represent a function.

If a belongs to A then some a b belongs to r. 2Determain whether the following relation is a function.
