Exponential and Logarithmic Functions
Exponential Functions and their Graphs:
Exponential Functions have variables as a power instead of a base and numbers as a base instead of a power
The standard form for an exponential function is f(x)=a•b²
a
cannot equal zero and b is a positive number other than 1
a is the initial value and b the base
To graph an exponential function proceed to make an x and
Properties of Logarithms:
The Product Rule:
The product rule states that every log added is multiplied and every log multiplied is adde
The Quotient Rule:
The quotient rule states that every log equation subtracted is divided and every log equation divided is subtracted
The Power Rule:
The power rule states that logarithmic powers can move positions on the equation as long as it still means the same thing
When a log is
Logarithmic Functions and their Graphs:
A Logarithm is a power to which the number must be raised to get to another number
Solving Exponential and Logarithmic Equations:
By using the Product, Quotient, and power rule it's simple to solve a logarithmic equation
Common Logarithm and Change of Base:
