Answer:
Last option: It is not a function because there are two different y-values for a single x-value.
Step-by-step explanation:
It is necessary to remember that, by definition, a relation is a function if each input value (x-value) has one and only one output value (x-value) .
In this case, the following points:
You can observe that the input value 4 (
) has two ouput values. These are:
Therefore, since there are two different y-values for a single x-value, you can conclude that the given graph is not a function.
Answer: SECOND OPTION
Step-by-step explanation:
By definition the domain is the set of value of the input (x values) shown in the table attached in the problem.
By definition the domain is the set of value of the output (y values) shown in the table attached in the problem.
Therefore, keeping the above on mind, you have:
Domain:{-2,-1,0,1,2,3}
Range:{-8,-1,0,1,8,27}
To determine the cost of each meter of the ribbon, we divide the cost for 5 meters of ribbon by 5. That is,
x = $4 / 5
where x is the cost of each meter. Simplifying will give us an answer of $0.8/m. Converting this to per mm.
($0.8/m) x (1 m/ 1000 mm)
= $0.0008/mm
It's true. It must equal 180 degrees and the only way to accomplish that while it being an equilateral triangle is by having only one triangle! :)
I am pretty sure it is a because 2 is half of 4 and 18 is half of 36.
