Answer:
This function would be even.
Step-by-step explanation:
You can tell a function is even if you plug in -x for x and then simplify and it is the same function. This is the case below.
y = 2x^4 + 2x^2 ----> Plug in -x
y = 2(-x)^4 + 2(-x)^2 ----> Simplify
y = 2x^4 + 2x^2
You'll notice the simplified version is exactly the same as the original, which makes it odd.
