This figure shows a representation of the growth of a bacterium in the presence of antibiotic B. The horizontal axis is labelled time and the vertical axis is labelled log (no. of viable cells). The line crosses the vertical axis near the bottom before sloping upwards. The arrow indicates the timepoint at which antibiotic B was added. After the arrow the line slopes sharply towards the horizontal axis.
