Question

F(x)=x3 −4x even odd or neither

Answer 1

The function would be odd

Answer 2

The answer is neither.

Let's take an odd number and substitute.

• f(3) = 3³ - 4(3)
• f(3) = 27 - 12
• f(3) = 15 (odd)

Now, let's take an even number.

• f(4) = 4³ - 4(4)
• f(4) = 64 - 16
• f(4) = 48 (even)

Since both even and odd numbers are possible, it is neither.
