Ascientist begins an experiment with a petri dish containing a culture of bacteria cells and records the cell growth every hour. at 1 hour, the bacteria had grown to 880 cells, and at 2 hours, had grown to 3,520 cells. which function can be used to represent the relationship between the number of bacteria cells, y, and the time in hours, x?
y = 4 x
y = 220(4) x
y = 880(4) x
y = 880(0.25) x
