Alissa is currently a teacher in the San Francisco Bay Area and Brightstorm users love her clear, concise explanations of tough concepts

If you know the basic parent graph, asymptote, and a few key points for f(x)=log x, you can quickly graph log functions using transformation rules. In f(x) = alog(x - b) + c , negative "a" represents a reflection across the x axis, "b" represents a horizontal shift (take the asymptote, too!) and "c" represents a vertical shift. If you get lost, plug in a few values for x and find the corresponding y values to get some points on the graph.
