1.Henrietta did an experiment. She started out with 800 bacteria cells. She found that the growth rate of the bacteria cells was 3.2%. Sketch the graph that represents the situation marking what the axes represent. Make sure to clearly label the y-intercept and the point that represents the projected bacteria population at 35 hours from the time Henrietta started the experiment. Show any calculations that are needed to find the points.
