Construct a table of values and graph the inverse of this logarithmic function, the exponential function f –1(x) = 2x. Example 5 Graphs of Logarithmic Functions Since f (x) = log2x and f …

Establish that when a is greater than 1 the graph shows an exponential increase for positive values of x. When a is between 0 and 1, the graph shows an exponential decrease for positive …

Properties of Logarithms There are four basic properties of logarithms that we will be working with. For every case, the base of the logarithm can not be equal to 1 and the values must all …

x log b 0 is not defined log b (-x) is not defined For x > 0 and b 1,

In this equation, y = logax, where a = 2. y = log2x means x = 2y. Using x = 2y, construct a table of values. The domain, is {x|x > 0} and the range is (-∞, ∞).

interpretation Characteristics of graph of y = ln x The second derivative of ln x is The second derivative is always negative. ln x is always concave down. ln x is an antiderivative of 1/x .
