Question

Determine whether the function f(x) = 3x is even or odd.

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

Answer 1

Answer: The function is even because
`f(x)=f(-x)`.

Explanation:

`f(x)=3x^4 \\\\f(-x)=3(-x)^4 = 3x^4\\\\\therefore f(x)=f(-x)`

So, the function is even.
