$- 4$

#### Explanation:

Given: $f \left(n\right) = {n}^{2} - 4$

When $f \left(0\right)$, we simply plug in $n = 0$ into the function, and we get,

$f \left(0\right) = {0}^{2} - 4$

$= 0 - 4$

$= - 4$

$- 4$

#### Explanation:

Substitute $0$ for $n$ in the expression ${n}^{2} - 4$

$f \left(0\right) = {\left(0\right)}^{2} - 4 = 0 - 4 = - 4$
