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?
Look this american “ñ” hahaha
Amayo943,
Remember that with exponents you have to multiply the number of exponets by the same number it's in for example:
In this case you need to know that:
Therefore your answer is "225."
Hope this helps!

cone has no parallel bases all the others do
Answer:
(c) 43.
Step-by-step explanation:
Given:
Margin of error (E) = 2
Sample variance
= 44
Confidence level = 95%
The z- value at 95% confidence level is 1.96.
The sample using the provided information can be calculated as:

Hence, the correct option is (c) 43.
