From Thinkwells College AlgebraChapter 6 Exponential and Logarithmic Functions Subchapter 62 Logarithmic Functions. On the other hand the logarithmic function is defined as the inverse function of exponentiation. Returns the smallest integral value thats greater than or equal to the specified Decimal or Double.
It is how many times we need to use 10 in a multiplication to get our desired number.
Lets use this information to set up our log. Logarithm the exponent or power to which a base must be raised to yield a given number. If the data lies on a straight line or seems to lie approximately along a straight line a linear model may be best. In the same fashion since 10 2 100 then 2 log 10 100.
