Answer

# Explanation: ## Step1: Identify the integrand The integrand is the function being integrated. Here, it is $9z^{2}-7z - 2$. ## Step2: Identify the lower - bound The lower - bound is the number at the bottom of the integral sign. So, it is $-9e$. ## Step3: Identify the upper - bound The upper - bound is the number at the top of the integral sign. So, it is $2.1$. ## Step4: Identify the variable of integration The variable of integration is the variable next to $d$ in the integral. Here, it is $z$. # Answer: The integrand is $9z^{2}-7z - 2$, the lower bound is $-9e$, the upper bound is $2.1$, and the variable of integration is $z$.
