Answer:
i say A because you cant add W with 12 nor 16 and its not D because the W needs to be squared
X= -0.6.........no work needed there is no equation
2 is the only right answer. If it has right/left symmetry, then f(-x) = f(x), meaning it's even.
extra info: 3 and 4 are the same thing
5 works for odd functions (like sin(x))
