Answer 1

Answer:

The correct answer is option B. Tom's work is incorrect. He made a mistake in step 1.

Explanation:

We are given the function:

$f(x)=x^3+x$

When he did the calculations for f(-x), he only replaced the x in the cubic term.

The correct step 1 is:

$f(-x)=(-x)^3+(-x)$$f(-x)=-x^3-x$

And now, we can see that:

$f(-x)=-f(x)$

Thus, the function is ODD.
