Select one:
O a. f(3) = (1 + 5)2 + 9
O b. f(0) = (x - 5)2 + 9
O c. f(1) = -(x + 5)2 + 9
O d. S(0) = -(0 - 5)+ 9

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
