Question

If f(n) n2 - 2n, then f(2) = 0. True.or.False?

Answer 1

true

Explanation:

if you substitute n for 2

(2)(2) = 4

(2)(2) = 4

4 - 4 = 0

Answer 2

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!
