The video tutorial explains how to find the intersection point of two functions, f(x) = (8x + 1)/3 and g(x) = 2x + 3. It begins by setting up the equation f(x) = g(x) to find the x-coordinate of the intersection. The tutorial then demonstrates solving the equation by eliminating fractions and simplifying to find x = 4. Next, it calculates the y-coordinate by evaluating f(4) and g(4), both yielding 11, confirming the intersection point at (4, 11). The video concludes with a verification using a graphing utility.

What is the main goal of the problem discussed in the video?

• To determine the intersection point of f(x) and g(x)
