You simply make $n$ $n$ equal to 3.

You know that your function looks like this

$k (n) = 2 n^{2}$ $k(n) = 2n^2$

This means that, for any value of $n$ $n$ , you need to square this value and multiply it by 2 to get the value of the function.

This means that $k (3)$ $k(3)$ , which simply means that you evaluate the function when $n = 3$ $n=3$ , will be equal to

$k (3) = 2 \cdot 3^{2} = 2 \cdot 9 = 18$ $k(3) = 2 * 3""^2 = 2 * 9 = color(green)(18)$
