Understanding X-Intercepts and Initial Values

This video tutorial explains how to find the initial value and x intercept of a function using a table. The initial value, also known as the Y intercept, is the range value when the domain is zero. Conversely, the x intercept, also called a zero or root, is the domain value when the range is zero. The video guides viewers through identifying these values in a table, demonstrating the process with examples.
