WebIn other words, F is proportional to the logarithm of x times the slope of the straight line of its lin–log graph, plus a constant. Specifically, a straight line on a lin–log plot containing points (F 0, x 0) and (F 1, x 1) will have the function: () = [⁡ (/) ⁡ (/)] + = ⁡ +log–linear plot. On a log–linear plot (logarithmic scale on the y-axis), pick some fixed point (x 0, F … WebSo with that out of the way, x gets as large as 25. So let me graph-- we put those points here. So that is 5, 10, 15, 20, and 25. And then let's plot these. So the first one is in blue. When x is 1/25 and y is negative 2-- When x is 1/25 so 1 is there-- 1/25 is going to be really close to there-- Then y is negative 2.
