Answer:

True

Explanation:

We are given the function:


f(n)=n^2-2n

And we are asked to verify whether f(2) = 0 is true or false statement.

To do so, we can let n = 2. Thus:


f(2)=(2)^2-2(2)

Square and multiply:


f(2)=4-4

Subtract:


f(2)=0

So, the statement is indeed true.

And we're done!
