Question

Use the graph to determine the domain and range of the relation and whether that relation is a fuction

Answer 1

Domain: {x| –10, –8, –6, –4, –2, 0, 2, 4, 6, 8, 10}
Range: {y| –6, –5, –1, 1, 3, 4, 5, 7, 8, 10}
Yes, the relation is a function.

Domain: {x| –10 x10}
Range: {y| –6 y10}
Yes, the relation is a function.

Domain: {x| –10 x10}
Range: {y| –6 y10}
No, one y-value is shared by two x-values.

Domain: {x| –10, –8, –6, –4, –2, 0, 2, 4, 6, 8, 10}
Range: {y| –6, –5, –1, 1, 3, 4, 5, 7, 8, 10}
No, one y-value is shared by two x-values.

Answer 2

domain: [-10, 10]
range: [-6,10]
Yes, relation is a function.

Answer 3

One y-value is shared by 2 x-values? Isnt that a function as well? Or did I memorised wrongly?

Answer 4

The relation is a function because no two of its ordered pairs have the same first member or x value.

Answer 5

Range = (y: 10>y>-6)
Domain = ( x : 10> x>-10)

Answer 6

I got it wrong it was A
Domain: {x| –10, –8, –6, –4, –2, 0, 2, 4, 6, 8, 10}
Range: {y| –6, –5, –1, 1, 3, 4, 5, 7, 8, 10}
Yes, the relation is a function.

Answer 7

remember that for a graph to be a graph of a function it must have for every x-value only one y-value.

Answer 8

You can also read what is not given to you from the graph provided.
