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

Lady_Fox [76]

Answer:

True

Step-by-step explanation:

So we know that:

$f(n)=n^2-2n$

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

To determine the answer, substitute 2 for n in the function and solve. So:

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

Square and multiply:

$f(2)=4-4$

Subtract:

$f(2)=0$

So, the statement is indeed true.

And we're done!
