Evaluating functions for numeric values

The video tutorial explains how to evaluate a polynomial function P of X = 2X^2 - 4X + 1 at specific values of X. It begins with an introduction to the function and the task of finding P(2) and P(-1). The tutorial then reviews basic function concepts using F of X = X + 1 as an example. It proceeds to demonstrate the evaluation of P at X=2, emphasizing the order of operations. Finally, it shows the evaluation of P at X=-1, highlighting the handling of negative inputs.
