Math Problem Statement

Write the logarithmic and exponential equations associated with the given graph of g(x) = ln(x), and identify the logarithmic equation for a point with coordinates (X = 2.76, Y = 1.0152307).

Solution

From the image, we see a graph of the natural logarithmic function g(x)=ln(x)g(x) = \ln(x). The point marked on the graph has the coordinates (X=2.76,Y=1.0152307)(X = 2.76, Y = 1.0152307). The task is to write the logarithmic equation associated with the displayed point.

The general form of the logarithmic equation is:

Y=ln(X)Y = \ln(X)

Using the point provided (X=2.76,Y=1.0152307)(X = 2.76, Y = 1.0152307), we can directly substitute the XX-value into the equation:

Y=ln(2.76)Y = \ln(2.76)

We can verify the logarithmic equation by checking if ln(2.76)\ln(2.76) equals the given YY-value 1.01523071.0152307. Indeed, this is approximately true since:

ln(2.76)1.0152307\ln(2.76) \approx 1.0152307

Thus, the logarithmic equation is:

Y=ln(2.76)Y = \ln(2.76)

Would you like to go over the exponential counterpart of this equation or any other details?

Here are 5 related questions for further exploration:

  1. What is the inverse of the logarithmic function Y=ln(X)Y = \ln(X)?
  2. How do we rewrite the equation Y=ln(X)Y = \ln(X) in exponential form?
  3. What is the derivative of g(x)=ln(x)g(x) = \ln(x)?
  4. How do the properties of logarithms apply when solving equations like ln(ab)\ln(a \cdot b)?
  5. What happens to ln(x)\ln(x) as x0+x \to 0^+ or xx \to \infty?

Tip: The natural logarithm ln(x)\ln(x) is defined only for positive xx-values, which is why the graph only appears for x>0x > 0.
