The domain the function is .
In interval notation: [7, ∞).
The range of the function is in the interval (1, ∞).
The given function is .
The domain is x ≥ and the range is y ≥.
<h3>What is a function?</h3>A technical definition of a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Now,
⇒
Therefore, the domain the function is
The range of the function is the set of all values of y when we substitute the values of x.
Now, for
So, the value of y in the interval (1, ∞).
Therefore, the range of the function is in the interval (1, ∞).

Answer:
x = 0.8
Step-by-step explanation:
If you mean y = √(1 -x²), then the curves cross at x=0.8.
__
If you equate the y-expressions, then square both sides, you have ...
√(1-x²) = 2x-1
1 - x² = (2x -1)² = 4x² -4x +1
0 = 5x² -4x . . . . . subtract the left-side expression
x(5x -4) = 0 ⇒ x = 0, or x = 4/5
The x=0 solution is extraneous.
The two equations are equal at x = 4/5.
