The video tutorial walks through problem 15, which involves analyzing a differentiable function's graph. The task is to compare the values of H, H', and H'' at x=6. The instructor first calculates H(6) using the integral of f(t) from 0 to 6, determining it is less than zero. Then, using the fundamental theorem of calculus, H'(6) is found to be zero. Finally, the slope of the tangent line at x=6 is analyzed to conclude that H''(6) is greater than zero. The correct order of values is H(6) < H'(6) < H''(6).
