The graph of the function y=ln(x) is characterized by a gently increasing curve that passes through the point (1,0).
The natural logarithm function, ln(x), is defined exclusively for positive values of x. Consequently, its graph exists solely in the right half of the coordinate plane, where x>0. As x approaches 0 from the right, the value of y=ln(x) decreases indefinitely, tending towards negative infinity. This behavior results in a vertical asymptote at x=0, indicating that the graph approaches the y-axis but never intersects it.
At the point x=1, the natural logarithm of 1 is 0, which means the graph intersects at (1,0). This point is crucial for accurately sketching the graph. As x increases beyond 1, the value of y=ln(x) continues to rise, albeit at a decreasing rate. This implies that the graph ascends more slowly as x grows larger.
The overall shape of the graph is a smooth, continuous curve that starts from negative infinity as x approaches 0, passes through the point (1,0), and continues to rise gradually as x increases. Notably, the graph never touches or crosses the y-axis and extends infinitely to the right. Familiarity with these characteristics enables one to effectively sketch the graph of y=ln(x) and analyze its behavior in various mathematical contexts.
