Amal Kumar presents a video tutorial on finding x-intercepts of functions. The video includes four examples, each demonstrating different scenarios for calculating x-intercepts. The tutorial begins with an introduction and purpose, followed by detailed explanations of each example. The first example shows a straightforward calculation of x-intercepts, while the second example presents a tricky case with no intercepts. The third example involves solving for zeros, and the fourth example demonstrates finding x-intercepts in factored form. The video emphasizes understanding the concept of x-intercepts and provides step-by-step solutions.
