So, the semilogx function would not be sufficient. The crux is the fitted line through the data: changing the xscale to log moves the data points in the normplot fine, but the fitted line stays anchored to what
Understand how to evaluate logarithmic expressions, know how to solve logarithmic equations, and explore the various properties of logarithms that are used in evaluating logarithm problems. Related to this QuestionUse the definition of the logarithmic function to find x....
A logarithmic function has a domain of real numbers higher than zero and a range of real values. The graph of y = logax is symmetrical to the graph of y = ax with respect to the line y = x. This is true for any function and its inverse. A logarithmic function with base e is re...
No. Recall that the range of an exponential function is always positive. While solving the equation, we may obtain an expression that is undefined.Example 4: Solving an Equation with Positive and Negative Powers Solve 3x+1=−23x+1=−2. Show Solution Try...

Power Rule of Logarithms: The power rule of logarithms states that the exponent of a number being operated upon by a logarithm function can become the coefficient of the logarithm of the base number: ln(ab)=bln(a). The following two problems demonstrate...
Detailed Answers Part I Almost all of the problems in this part make use of the Fundamental Duality that exists between the log function and the exponential function: log v a u v a u = ⇔ = For the log function on the left, the quantity u is the argument of the log function...
Use logarithmic differentiation to find the derivative of the function y= (sin 3x)^{ln x} Find y' if x^y = Y^x Differentiate the function g(x) = ln(x squareroot {x^2 - 12}) Explore our homework questions and answers library ...
• 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(...
Most often, we need to find the derivative of a logarithm of some function ofx. For example, we may need to find the derivative ofy= 2 ln (3x2− 1). We need the following formula to solve such problems. If y= lnu anduis some function ofx, then: ...
