Answer:

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

Step-by-step 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.
