Calculate the derivative indicated.
where
We need to find the derivative of the given function, P(V), and evaluate the derivative at V = -6.
The power rule for finding derivatves is , for all exponents n.
In order to use the power rule, write as 7·Vn for some n.
where n =.
Write the expression -7·V-2 without the negative exponent.
Now evaluate at V = -6 (to two decimal places).
