Given the -intercept is the point existing on the line is. We can then form 3 equations in 3 unknowns and solve them to get the required result. Initially well need to estimate the length of the curve.

The derivative is undefined at x 0 but there is in fact a tangent line there even though the software doesnt draw it because it uses the derivative to find the slope of the tangent line which is undefined at this point. Curve fitting is one of the most powerful and most widely used analysis tools in Origin. The clearest indicators to check these answers with are 1 points where a function crosses zero compared to where another function has zero slope and 2 where a function is increasing compared to where another function is positive. We can then form 3 equations in 3 unknowns and solve them to get the required result.
