The video tutorial explains how to evaluate functions of two variables. It demonstrates the process using two examples: F(4,4) and F(2,8). The tutorial walks through substituting values into the function, calculating powers and square roots, and simplifying expressions to find the function values. The video aims to help viewers understand the steps involved in evaluating such functions.

What is the function f(x, y) that we are evaluating?

• f(x, y) = x^(1/4) * sqrt(y)

• f(x, y) = x^(1/3) * sqrt(y)

• f(x, y) = x^(1/5) * sqrt(y)

• f(x, y) = x^(1/2) * sqrt(y)
