Which function has a domain where [tex]\(x \neq 3\)[/tex] and a range where [tex]\(y = 2\)[/tex]?

A. [tex]\( f(x) = -\frac{(x-5)}{(x+3)} \)[/tex]
B. [tex]\( g(x) = \frac{2(x+5)}{(x+3)} \)[/tex]
C. [tex]\( h(x) = \frac{2(x+5)}{(x-3)} \)[/tex]
D. [tex]\( k(x) = -\frac{(x+5)}{(x-3)} \)[/tex]



Answer :

To determine which function satisfies [tex]\( y = 2 \)[/tex] when [tex]\( x = 3 \)[/tex], we'll evaluate each given function at [tex]\( x = 3 \)[/tex] and see if the result equals [tex]\( 2 \)[/tex].

### Function 1: [tex]\( -\frac{(x-5)}{(x+3)} \)[/tex]

Evaluate at [tex]\( x = 3 \)[/tex]:
[tex]\[ -\frac{(3-5)}{(3+3)} = -\frac{(-2)}{6} = \frac{2}{6} = \frac{1}{3} \][/tex]
This does not equal [tex]\( 2 \)[/tex].

### Function 2: [tex]\( \pi(x) = \frac{2(x+5)}{(x+3)} \)[/tex]

Evaluate at [tex]\( x = 3 \)[/tex]:
[tex]\[ \frac{2(3+5)}{(3+3)} = \frac{2(8)}{6} = \frac{16}{6} = \frac{8}{3} \][/tex]
This does not equal [tex]\( 2 \)[/tex].

### Function 3: [tex]\( f(x) = \frac{2(x+5)}{(x-3)} \)[/tex]

Evaluate at [tex]\( x = 3 \)[/tex]:
[tex]\[ \frac{2(3+5)}{(3-3)} = \frac{2(8)}{0} \][/tex]
This is undefined, as division by zero is not possible.

### Function 4: [tex]\( -\frac{(x+5)}{(x-3)} \)[/tex]

Evaluate at [tex]\( x = 3 \)[/tex]:
[tex]\[ -\frac{(3+5)}{(3-3)} = -\frac{8}{0} \][/tex]
This is undefined, as division by zero is not possible.

Since none of the functions return [tex]\( y = 2 \)[/tex] when [tex]\( x = 3 \)[/tex], there seems to be no function from the set provided that satisfies both [tex]\( x = 3 \)[/tex] and [tex]\( y = 2 \)[/tex].

### Conclusion:
None of the functions provided has both an appropriate domain where [tex]\( x = 3 \)[/tex] and a range that includes [tex]\( y = 2 \)[/tex].
