Determine algebraically whether or not the function f(x)=3x^2/1-x^4, is even or odd and justify your answer

A. The function is odd because f(-x) = -f(x)

B. The function is odd because f(-x) = f(x)

C. The function is even because f(-x) = -f(x)

D. The function is even because f(-x) = f(x)

E. The function is neither even nor odd because because f(-x) does not equal f(x) and f(-x) does not equal -f(x)
