Determine if the function is an even function, an odd function or neither.

Answer: Option a.
Step-by-step explanation:
By definition, a functioon is even when:
[tex]f(x)=f(-x)[/tex]
And it is odd when:
[tex]-f(x)=f(-x)[/tex]
Therefore, you can verify if the function is even substituting -x into the function:
[tex]f(-x)=2(-x)^{4}+2(-x)^{2}\\f(-x)=2x^{4}+2x^{2}[/tex]
Then:
[tex]-f(x)=f(-x)[/tex]
It is an even function.
Answer:
Choice A is correct.
Step-by-step explanation:
We have given a function.
y = 2x⁴ +2x²
suppose y = f(x) , we get,
f(x) = 2x⁴ +2x²
We have to find that is this function is even or odd?
A function is even if f(x) = f( -x).
A function is odd if f(x) = - f(x).
Putting x = -x in f(x) we get,
f(-x) = 2(-x)⁴+2(-x)²
f(-x) = 2x⁴+2x²
f(-x) = f(x)
So, the function is even.
