Today’s quiz focused on the interpretation of our notation: \(\displaystyle\int_a^b f(x)\, dx\). This notation refers to the area between \(f(x)\) and the \(x\)-axis, from \(x=a\) to \(x=b\).

Today’s quiz covered the Riemann Sum. The given function was \(f(x) = x^2 – 9\), and you were asked to identify where the function intersected the \(x\)-axis. These two intersections were then used as the start and end of our interval for approximating the area bounded by \(f(x)\).

Today’s lesson started with students requesting to see problems from the Exam 1 Review sheet. We did several before proceeding to talk about the new unit — what will come after Exam 1.
