Answer:

  A.  neither even nor odd

Step-by-step explanation:

The equation is that of a parabola whose line of symmetry is x=-5. Even functions are symmetrical about the line x=0, so this is not an even function. It has terms of even degree, so is not an odd function.

The function is neither even nor odd.

Answer:

Option A - neither even nor odd

Step-by-step explanation:

Given : [tex]f(x)=(x+5)^2[/tex]

To find : Determine whether the function below is an even function, an odd function, both, or neither ?

Solution :

We know that,

1) If f(-x)=f(x) it is an even function.

2) If f(-x)=-f(x) it is a odd function.

[tex]f(x)=(x+5)^2[/tex]

[tex]f(x)=x^2+10x+25[/tex]

Substitute x with -x in the function,

[tex]f(-x)=(-x+5)^2[/tex]

[tex]f(-x)=x^2-10x+25[/tex]

The function does not comply with the definitions.

The function is neither even  nor odd.

Therefore, option A is correct.
