The general form for a logarithmic function is [math]y=a\cdot log_b\left(x-h\right)+k.[/math] The equation [math]x=h[/math] represents the vertical asymptote of the graph that creates a boundary line on the right or left side of the logarithmic graph.[br][br]Please use the sliders below to see what happens when the a, b, h, and k values are increased and decreased.[br][br]You can reset the graph to its original position by clicking the circular arrow in the upper right corner of the graph.
