Determining the Difference Quotient

The video tutorial explains how to evaluate a function F(x) = x^2 - x + 1 using the difference quotient. It covers evaluating the function for 2 + H and 2, and then simplifying the difference quotient. The final result is expressed as H + 3, with the constraint that H cannot be zero. The tutorial provides a step-by-step approach to understanding the process, preparing students for more advanced calculus concepts.

Explain the process of finding the difference quotient as mentioned in the text.

What does the final answer of the evaluation represent when H cannot equal 0?
