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 $z$.
