Question

PLEASE HELP! I HAVE NO IDEA HOW TO SOLVE THIS!!!

Find the domain and range of the relation and determine whether it is a function.

Answer 1

Hold on I have a graph to upload...

Answer 2

Ok

Answer 3

Is that all the information given ? Like is there a problem given . For Example f(x)=2x+3 Something like that ?

Answer 4

Sorry that's all that they gave me. I can give you the answer choices though.

domain: x > 1; range: y > 0; Yes, it is a function.
domain: all real numbers; range: all real numbers; Yes, it is a function.
domain: positive integers; range: positive integers; No, it is not a function.
domain: x ≥ 0; range: y >1; No, it is not a function.

Answer 5

The graph shows that there are no y-values before x = 1; the domain of the graph is the x-values for which the graph exists. In this case, x > 1.
The range of the graph is a little bit easier to see; it is the possible y-values the function can take.
The graph will only be a function if a single y-value is generated for each x-value. More than one y-value (e.g. like those found on a graph of a circle) for a single x-value means the graph is not a function.

See if that helps :)

Answer 6

I still don't understand. How do you know what the x and y values are?

Answer 7

The domain is a little hard to spot on the graph.
