Answer 1

odd

Explanation:

To determine if odd/ even

• If f(x) = f(- x) then it is even

• If f(- x) = - f(x) then it is odd

Given

f(x) = 4x³ - 5x , then

f(- x) = 4(- x)³ - 5(- x) = - 4x³ + 5x

Since f(x) ≠ f(- x) then it is not even

- f(x) = - (4x³ - 5x) = - 4x³ + 5x

Since f(- x) = - f(x) , then 4x³ - 5x is odd
