In general, the domain is the set of all x-values for the graph.
The issue here is that this isn't the graph of a function. A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.
So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.
The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?
Answer:
The first three statements are correct, the other two are wrong
Second to last problem: WRONG - Since the second to last problem is marked down by 40% we subtract 40% from 100% to get 60%. Now we just do 0.60*28 = 16.8 which makes the statement wrong.
Last problem: WRONG - The last one is marked down by 50% so that is 100% - 50% to get 50%. We do 0.50 * 28 to get 14, making the statement wrong.
The first 3 statements are correct, and the 2 last ones are wrong
- Hope this helped! :)
Brainiest is most appreciated:)
The answer would be 6x+42
