Step 1:
: Understand the form of the logarithmic function

A general logarithmic function has the form f(2$) = log\_b(2$), where b is the base of the logarithm. To graph this function, it's essential to understand its domain, range, and asymptote. The domain is x > 0, the range is all real numbers, and the vertical asymptote is x = 0.

Step 2:
: Find key points and intercepts

To graph the function, find a few key points by setting the argument of the logarithm (x) equal to some powers of the base (b). For example, if f(2$) = log\_2(x), you can find the following points: f(2$) = log\_2(1) = 0 f(2$) = log\_2(2) = 1 f(2$) = log\_2(4) = 2 f(2$) = log\_2(8) = 3 These points help you visualize the shape of the graph and serve as a guide for drawing it.

Step 3:
: Determine the vertical asymptote

The vertical asymptote of a logarithmic function is always at x = 0. This is because the logarithm of any number less than zero is undefined. In the context of the function's domain, x must be positive, so x = 0 is the vertical asymptote.

Step 4:
: Sketch the graph using the key points and asymptote

Connect the key points you found in Step 2 with a smooth curve, ensuring that the curve approaches the vertical asymptote as x approaches zero. The curve should be increasing if the base is greater than 1 and decreasing if the base is between 0 and 1.

Step 5:
: Label the graph and verify accuracy

Label the graph with the function name, the base, the vertical asymptote, and any important points. To ensure accuracy, check that the graph passes through the key points and approaches the vertical asymptote correctly.

Final Answer

Label the graph with the function name, the base, the vertical asymptote, and any important points. To ensure accuracy, check that the graph passes through the key points and approaches the vertical asymptote correctly.
