Steps Using Derivative Rule for Sum

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is $0$. The derivative of $ax^{n}$ is $nax^{n-1}$.

$$9z^{1-1}$$

Subtract $1$ from $1$.

$$9z^{0}$$

For any term $t$ except $0$, $t^{0}=1$.

$$9\times 1$$

For any term $t$, $t\times 1=t$ and $1t=t$.

$$9$$
