Warm-Up A biologist is studying the exponential growth of a colony of bacterial cells. The table gives the number of cells, y, in the
colony over time, x, in hours.
Time, x (hours) Number of Cells, y
100
1
200
2
400
h
6,400
Replace the values of A, b, x, and y to write an exponential equation that represents the number of cells present at h hours.
