Math Problem Statement
The coordinates of a point on the graph of the indicated function, shown to the right, are displayed at the bottom of the screen.
Write the logarithmic and exponential equations associated with the display.

A coordinate system has a horizontal x-axis labeled from negative 1 to 10 in increments of 1 and a vertical y1=ln(x)-axis labeled from negative 3 to 3 in increments of 2. From right to left, a curve labeled g(x) = ln x falls at an increasing rate, passing through the points (10, 2.3), the plotted point marked with an X at (3, 1.1), and (1, 0). As x approaches 0 from the right, the curve approaches negative infinity. At the bottom of the screen X=2.95 and Y=1.0818052 are labeled. All coordinates are approximate.

Solution
Based on the description, the logarithmic equation associated with the graph is the natural logarithm function. Since the graph follows the curve of and the coordinates at the bottom are and , these values represent a point on the curve .
Thus, the logarithmic equation is:
In this case, with and , this satisfies the equation , which approximately equals 1.0818052.
