When using a logarithmic scale, the vertical distance between the prices on the scale will be equal when the percent change between the values is the same. Using the above example, the distance between $10 and $15 would be equal to the distance between $20 and $30 because they both represent a price increase of 50%.

In this lesson, we will prove three logarithm properties: the product rule, the quotient rule, and the power rule. Before we begin, let's recall a useful fact that will help us along the way. In other words, a logarithm in base b reverses the effect of a base b power!

Definition of logarithmic scale : a scale on which the actual distance of a point from the scale's zero is proportional to the logarithm of the corresponding scale number rather than to the number itself compare arithmetic scale.

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.

The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. y = logax only under the following conditions: x = ay, a > 0, and a22601. It is called the logarithmic function with base a. Consider what the inverse of the exponential function means: x = ay.

For example, 32 = 2 × 2 A— 2 A— 2 A— 2 = 22. The exponential function 22 is read as two raised by the exponent of five or two raised to power five or two raised to the fifth power. Then the logarithmic function is given by; f(x) = log b x = y, where b is the base, y is the exponent, and x is the argument.
