1) The domain of any logarithm function of the form f(x)=logB(x)f(x)=logB(x) is the set of all real positive numbers. In inequality form the domain is: x>0x>0 and in interval form it is given by: (0,+∞)(0,+∞).
derivative of the exponential functionDefining the logarithmic function as a definite integral with a variable upper limit, an approach used by some popular calculus textbooks, is problematic. We discuss the disadvantages of such a definition and provide a way to fix the problem. We also consider ...

A logarithmic function has the form $$f(x) = \log_b x $$ for some base {eq}b>0 {/eq}. In other words, the value of the function at every point {eq}x {/eq} is equal to the logarithm of {eq}x {/eq} with respect to a fixed base. The graphs of several logarithmic functi...
In the last section we learned that the logarithmic function y=logb(x)y=logb(x) is the inverse of the exponential function y=bxy=bx. So, as inverse functions:The domain of y=logb(x)y=logb(x) is the range of y=bxy=bx:(0,∞)(0,∞). The range of y=logb(x)y=logb(x) is ...
The inverse of an exponential function is a logarithmic function, and the inverse of a logarithmic function is an exponential function. Logarithmic equations can be written in an equivalent exponential form using the definition of a logarithm. Exponential equations can be written in an equivalent ...
• Integral of a Logarithmic Function: The integral of logb(x)logb(x) with respect to x is: ∫logb(x)dx=xlogb(x)−xln(b)+C∫logb(x)dx=xlogb(x)−ln(b)x+C • Logarithmic Inequalities: The Logarithmic functions can be used to solve inequalities. For example, to solve logb(...
Since the unknown x appears in a log function (a log base 2 function in this example), then we have a logarithmic equation. How do you solve Logarithmic Equations? Solving logarithmic equations does not follow a set-in-stone sequence of steps, but instead, we need to be mindful of the ...
