The graph of [tex]f(x) = \sqrt{x}[/tex] is reflected across the [tex]x[/tex]-axis and then across the [tex]y[/tex]-axis to create the graph of function [tex]g(x)[/tex]. Which statements about the functions [tex]f(x)[/tex] and [tex]g(x)[/tex] are true? Check all that apply.

A. The functions have the same range.
B. The functions have the same domains.
C. The only value that is in the domains of both functions is 0.
D. There are no values that are in the ranges of both functions.
E. The domain of [tex]g(x)[/tex] is all values greater than or equal to 0.
F. The range of [tex]g(x)[/tex] is all values less than or equal to 0.



Answer :

To analyze the given problem, let's construct the functions step by step and evaluate each statement regarding [tex]\( f(x) = \sqrt{x} \)[/tex] and its reflection [tex]\( g(x) \)[/tex].

1. Reflecting [tex]\( f(x) = \sqrt{x} \)[/tex] across the x-axis:

Reflecting a function across the x-axis involves changing the sign of the function's output:
[tex]\[ h(x) = -\sqrt{x} \][/tex]

2. Reflecting [tex]\( h(x) = -\sqrt{x} \)[/tex] across the y-axis:

Reflecting a function across the y-axis involves changing the sign of the function's input:
[tex]\[ g(x) = h(-x) = -\sqrt{-x} \][/tex]

However, this function as given is defined for [tex]\( x \leq 0 \)[/tex] because the square root function is only defined for non-negative inputs. Thus:

[tex]\[ g(x) = -\sqrt{-x} \][/tex]

With [tex]\( f(x) \)[/tex] and [tex]\( g(x) \)[/tex] defined, we can check each statement one by one.

### Statement Analysis:

1. The functions have the same range.

- The range of [tex]\( f(x) = \sqrt{x} \)[/tex] is [tex]\([0, \infty)\)[/tex].
- The range of [tex]\( g(x) = -\sqrt{-x} \)[/tex] is [tex]\((-\infty, 0]\)[/tex].

These ranges are different, so this statement is false.

2. The functions have the same domains.

- The domain of [tex]\( f(x) = \sqrt{x} \)[/tex] is [tex]\([0, \infty)\)[/tex].
- The domain of [tex]\( g(x) = -\sqrt{-x} \)[/tex] is [tex]\([0, \infty)\)[/tex].

These domains are the same, so this statement is true.

3. The only value that is in the domains of both functions is 0.

- As mentioned, both functions are defined for [tex]\( x \geq 0 \)[/tex].

Thus, this statement is false. They share the entire interval [tex]\([0,\infty)\)[/tex], not just the point 0.

4. There are no values that are in the ranges of both functions.

- The range of [tex]\( f(x) \)[/tex] is [tex]\([0, \infty)\)[/tex].
- The range of [tex]\( g(x) \)[/tex] is [tex]\((-\infty, 0]\)[/tex].

There are no values common between these ranges, so this statement is true.

5. The domain of [tex]\( g(x) \)[/tex] is all values greater than or equal to 0.

- The domain of [tex]\( g(x) \)[/tex] is indeed [tex]\([0, \infty)\)[/tex].

So, this statement is true.

6. The range of [tex]\( g(x) \)[/tex] is all values less than or equal to 0.

- The range of [tex]\( g(x) \)[/tex] is indeed [tex]\((-\infty, 0]\)[/tex].

So, this statement is true.

### Conclusion

Based on the detailed analysis, the correct answers are:

- The functions have the same range. [tex]\(\quad (False)\)[/tex]
- The functions have the same domains. [tex]\(\quad (True)\)[/tex]
- The only value that is in the domains of both functions is 0. [tex]\(\quad (False)\)[/tex]
- There are no values that are in the ranges of both functions. [tex]\(\quad (True)\)[/tex]
- The domain of [tex]\( g(x) \)[/tex] is all values greater than or equal to 0. [tex]\(\quad (True)\)[/tex]
- The range of [tex]\( g(x) \)[/tex] is all values less than or equal to 0. [tex]\(\quad (True)\)[/tex]

Thus, the solution is:
[tex]\[ (0, 1, 0, 1, 1, 1) \][/tex]
