SUMMARY
The discussion focuses on finding the values of f(2) and f'(2) for the tangent line equation y=4x-5 at the point where a=2. The function under consideration is f(x)=x^2-1. The derivative f'(2) is determined to be 4, matching the slope of the tangent line, while the value of the function at that point, f(2), is calculated to be 3, which corresponds to the y-value of the tangent line at x=2.
