Answer 1

\[V(x) = x \left(\begin{matrix}16-x ^{2} \\ 4\end{matrix}\right)\]

Answer 2

multiply out the matrix first

Answer 3

whats a matrix?

Answer 4

what you have in the brackets

Answer 5

ok so i get \[v(x) = (16-x ^{2}) (4^{-1} ) (x)\]

Answer 6

Was that supposed to be a fraction \(\frac{16-x^2}{4}\)?

Answer 7

yes

Answer 8

Distribute your 'x' into the fraction, and then you can take the derivative.
