Question

How do you evaluate the function `k(n) = 2n^2`, for k(3)?

Answer 1

You simply make `n` equal to 3.

Explanation:

You know that your function looks like this

`k(n) = 2n^2`

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

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

`k(3) = 2 * 3""^2 = 2 * 9 = color(green)(18)`
