The logarithmic function, y=logb(x) , can be shifted k units vertically and h units horizontally with the equation y=logb(x+h)+k . If k>0 , the graph would be shifted upwards. If k<0 , the graph would be shifted downwards. If h>0 , the graph would be shifted left.

Semi-log Graph The x-axis has a linear scale, which means the ticks are evenly spaced. A semi-log graph is useful when graphing exponential functions. When graphed on semi-log paper, this function will produce a straight line with slope log (a) and y-intercept b.

Semi-log paper has one arithmetic and one logarithmic axis. The slope of the line (m) gives the exponential constant in the equation, while the value of y where the line crosses the x = 0 axis gives us k.

Log-log line — Both X and Y axes are logarithmic Slope is the change in log(Y) when the log(X) changes by 1.0. Yintercept is the Y value when log(X) equals 0.0. So it is the Y value when X equals 1.0.

This section is about the inverse of the exponential function. The inverse of an exponential function is a logarithmic function….Comparison of Exponential and Logarithmic Functions.

A logarithmic scale (or log scale) is a way of displaying numerical data over a very wide range of values in a compact way—typically the largest numbers in the data are hundreds or even thousands of times larger than the smallest numbers.

Logarithmic price scales are better than linear price scales at showing less severe price increases or decreases. They can help you visualize how far the price must move to reach a buy or sell target. However, if prices are close together, logarithmic price scales may render congested and hard to read.

An algorithm is said to run in quasilinear time (also referred to as log-linear time) if T(n) = O(n logk n) for some positive constant k; linearithmic time is the case k = 1. Quicksort, O(n log n), in its randomized version, has a running time that is O(n log n) in expectation on the worst-case input.

Yes, O(M+N) means the same thing as O(max(M, N)). Linear time is noted O(N). Since (M+N) is a linear function, it should simply be noted O(N) as well. Likewise there is no sense in comparing O(1) to O(2), O(10) etc., they’re all constant time and should all be noted O(1).

To elaborate, Time complexity measures the time taken to execute each statement of code in an algorithm. If a statement is set to execute repeatedly then the number of times that statement gets executed is equal to N multiplied by the time required to run that function each time.
