A bacterial colony has an initial population of 32.The population doubles every half-hour.
a)Write an equation that relates the population,p,to time,t,measured in 30-min intervals.
b)Sketch a graph of this relationship for 2 h.
c)Use the graph to determine the approximate population after 1h.Verify your answer using the equation.Which tool do you prefer to use?Explain why.
d)Determine the approximate population after 3.5h.Which tool do you prefer to use for this,the equation or the graph?Explain why.

a.等式因该是 P=32×2^2t (t的单位为小时)
b.画一个2小时内该等式的曲线.
c.问一小时后大概的细菌数量.问你更喜欢用图表还是等式,为啥?个人认为选图表,因为数值较小,可直观判断,快.
d.问你3.5小时后大概的细菌数量.问你更喜欢用图表还是等式,为啥?个人认为选等式,因为数值比较大,图表误差就大了,等式准确.
