title: Finding a point on a graph
body: <p>ok so I have a graph that has a steady increasing slope, much like an exponential graph. It then hits a point where the slope changes to a steep line, much steeper than a y=x graph. My question is, how do I find the point where the slope changes, whether it's VBA or just a function graph, I don't care, I just have no idea how to do this.</p>
