Question

Which set represents the same relation as the graph below? A B C D

Answer 1

Answer:

B. {( -1,-2 ), ( -3,-2 ), ( -5,4 ), ( 2,0 ), ( 3,3 ), ( 4,5 ), ( 6,-4 )}

Step-by-step explanation:

We are given the graph showing the points of a relation.

According to the graph, we see that, the given points of the relation are:

( -1,-2 ), ( -3,-2 ), ( -5,4 ), ( 2,0 ), ( 3,3 ), ( 4,5 ) and ( 6,-4 ).

As, we see that there are 7 points in the relation.

So, option C and D are not correct as they have 5 and 6 points respectively.

Also, option A is wrong as it contains different set of points.

Hence, we get that option B is correct.

That is the set representing the graphed relation is {( -1,-2 ), ( -3,-2 ), ( -5,4 ), ( 2,0 ), ( 3,3 ), ( 4,5 ), ( 6,-4 )}

Answer 2

Answer:

Option B

Step-by-step explanation:

The relation between two sets will be a subset of product set AxB

If represnted in ordered pair, x will be an element form A and y from set B.

Keeping this into mind, we must have the relation as (x,y) as ordered pair

WE see from the graph the points given are all in the option B

Hence option B is right

Option A is not right because first point (4,-5) is not appearing in the graph

OPtion C is not right because first point (-5,4) is in graph but (-3,-1) is not marked in the graph

Option D is not right because (4,-5) the first point itself is not in the graph
