1/125 or 0.008
fraction or decimal
Domain should be, (-♾️,♾️)
And range should be, (-♾️, 2)
If you ment something other then this please message me so I can help!
The domain of a function is the set of values of x in which the function can be calculated.
The range of a function is the associated values of the function respect to the domain.
You have the following function:

In order to determine the domain and range of the previous function, you consider that the given function is available for any value of x. Then, you have:
dom y: -∞ ≤ x ≤ ∞ : (-∞,∞)
The range of the function can be determine by noticing, on the graph, that the maximum value of the function is y=3 and also you can notice that there is no a limit for negatives values of the function. Then, you have:
ran y: -∞ ≤ y ≤ 3 : (-∞,3]
This equation has no solution.
Reason:
The absolute valued function, which is represented by straight bars, returns only positive values.
For example | - 5 | = 5
A negative result cannot be obtained from an absolute valued function. Since the given equation makes the absolute valued function equal to a negative value, which is not possible, so the equation has no solution or root.
343 = 7*7*7, so the square root is 7*sqrt(7), because there is one 7 left in the square root after taking out the other 2.
Final answer:
7*sqrt(7), or about 18.52
Hope I helped :)
