Understanding Intercepts and Multiplicity

In this video tutorial, the instructor continues from part one by focusing on finding the x-intercepts of a given function. The problem is set up with the function f(x) = (3x - 2)(x + 2)^2, and the instructor demonstrates how to solve for x-intercepts by setting the equation to zero. The solutions are x = 2/3 and x = -2. The concept of multiplicity is explained, highlighting how it affects the graph's behavior at the intercepts. The video concludes with a mention of the next part, which will cover end behavior.
