Logarithm the exponent or power to which a base must be raised to yield a given number. Use inverse operations to accomplish this. The graph approaches x 3 or thereabouts more and more closely so x 3 is or is very close to the vertical asymptote.
If a is less than 1 then this area is considered to be negative.
Log b x y log b x log b y Logarithm quotient rule. Log b x y log b x - log b y Logarithm power rule. In mathematics the logarithm is the inverse function to exponentiation. In this type the variable you need to solve for is inside the log with one log on one side of the equation and a constant on the other.
