Given:
The graph of a function.
To find:
The domain and range of the given graph.
Solution:
Domain is the set of x-values or input values.
From the given graph it is clear that, the graph is defined for the interval (-4,4).
But there is a closed circle at x = -4 and an open circle at x = 4. It means, -4 is included and 4 is not included in the solution set.
Domain: [-4,4)
Domain: 
Range is the set of y-values or output values.
From the given graph it is clear that, the output values are lie in the interval (-3,4).
But there closed circle at x = -3 and x = 4. It means, -3 and 4 are is included in the set of output values.
Range: [-3,4]
Range: 
Therefore, domain is and range is .
Answer:
The same inputs cannot have multiple different outputs
Yes? and what about it I’m confused about this question

Answer: Choice A, 29 degrees</h3>
Central angle CBA is a right angle, so it is 90 degrees. This means the arc measure from A to C, following the shortest path on the curve, is 90 degrees. This is minor arc CA. A minor arc is one that is less than 180 degrees in measure.
We want to find the measure of minor arc DE. This is the last piece of the puzzle, so to speak, that forms the entire arc ACD. This arc is 180 degrees because AD is a diameter.
So,
(minor arc DE) + (minor arc EC) + (minor arc CA) = arc ACD
x + 61 + 90 = 180
x + 151 = 180
x + 151 - 151 = 180 - 151 .... subtract 151 from both sides
x = 29
Minor arc DE is 29 degrees.

Answer:
Step-by-step explanation:
Given function is 
.
Now let's find it's range.
we know that square root function always gives positive output then:
Hence range of the function is ![(-\infty,8]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C8%5D)
.
we can repeat same process to find the range of all the given choices.
we will find that only 3rd choice has same range.
Hence final answer is
