Respuesta :
y = x + 4/x
replace x with -x. Do you get back the original equation after simplifying. if you do, the function is even. replace y with -y AND x with -x. Do you get back the original equation after simplifying. If you do, the function is odd. A function can be either even or odd but not both. Or it can be neither one. Let's first replace x with -x
y = -x + 4/-x = -x - 4/x = -(x + 4/x)
we see that this function is not the same because the original function has been multiplied by -1 . Let's replace y with -y and x with -x
-y = -x + 4/-x
-y = -x - 4/x
-y = -(x + 4/x)
y = x + 4/x
This is the original equation so the function is odd.
Answer:
Neither even nor odd.
Step-by-step explanation:
A functio f(x) is even if f(-x)=f(x) for all x in the domain.
A function f(x) is odd if f(-x)=-f(x) for all x in the domain.
First note that
[tex]f(x)=\dfrac{x+12}{x}[/tex]
hence
[tex]f(-x)=\dfrac{-x+12}{-x}=\dfrac{(-1)(x-12)}{(-1)x}=\dfrac{(x-12)}{x}\neq f(x)[/tex]
which tells us that the function is not even.
On the other hand,
[tex]-f(x)=-\dfrac{x+12}{x}=\dfrac{-x-12}{x}\neq f(-x)[/tex]
which tells us that the function is not odd.
Therefore, f(x) is neither even nor odd.
