ANSWER

g(-2) = 4

Step-by-step explanation

We are given the function g(n) as:


g(n)=2n^2\text{ - 4}

To find g(-2), we have to replace n with -2 in g(n) and simplify it.


\begin{gathered} g(-2)=2(-2)^2\text{ - 4 = 2}\cdot4\text{ - 4} \\ g(-2)\text{ = 8 - 4} \\ g(-2)\text{ = 4} \end{gathered}

That is the value of g(-2)
