Function Evaluation and Operations

The video tutorial explains how to evaluate and perform operations on functions F(x) = 2x - 3 and G(x) = 3x^2 + 5x + 1. It covers calculating F(2) + G(-2), G(6) - F(-3), F(4) x G(1), and G(9) / F(10) by substituting values into the functions and performing arithmetic operations. The tutorial emphasizes the importance of using parentheses to ensure correct order of operations.
