Solution 1

Sure, to determine whether the function is even, odd, or neither, we need to apply the definitions of even and odd functions.

An even function is a function for which f(x) = f(-x

Solution 2

Sure, to determine whether the function is even, odd, or neither, we need to apply the definitions of even and odd functions.

An even function is one where f(x) = f(-x) for all x in the domain of the function. An odd function is one where -f(x) = f(-x) for all x in the domain of the function.

Let's first check if the function is even:

f(-x) = 22(-x)^3 - 19(-x) = -22x^3 + 19x

This is not equal to f(x), so the function is not even.

Now let's check if the function is odd:

-f(x) = -(22x^3 - 19x) = -22x^3 + 19x

This is equal to f(-x), so the function is odd.

Therefore, the function 𝑓(𝑥) = 22𝑥^3 − 19𝑥 is odd.
