    Answer:

    An even function is:

    f(x) = 7

    Step-by-step explanation:

    An even function accomplish the following condition:

    f(x)=f(-x) (1)

    Applying (1), we have:

    • f(x)= (x-1)^2 \neq f(-x) \neq (-x-1)^2
    • f(x)= 8x \neq f(-x) \neq -8x
    • f(x)= x^2 -x \neq  f(-x) \neq (-x)^2 +x
    • f(x)=7 = f(-x)= 7

    The last one is even.
