The function f(x) = 8 is even because f(x)= f(-x).
Given the function is f(x) = 8
Key to find if a function f(x) is even or odd is to replace the x with -x.
if the results comes out to be f(x) then it is even function.
if the results comes out to be -f(x) then it is odd function.
where as graphically even f(x) will be symmetric around the y-axis and odd f(x) will be symmetric around the origin.
In given case f(x)= 8
if we replace x with -x in above equation then results is 7
f(-x)= 8
hence f(x)= f(-x) = 8
Therefore, f(x) = 8, is an even function.
