How to evaluate a radical function given three different values

The video tutorial explains how to evaluate a function F(x) = sqrt(3 - x^2) using specific examples. It starts with evaluating F(-2), highlighting the transition from real to imaginary numbers when dealing with negative square roots. The tutorial then evaluates F(0), emphasizing not to simplify sqrt(3). Finally, it evaluates F(1), resulting in sqrt(2). The focus is on understanding function evaluation and the implications of real and imaginary numbers.
