Question

A certain bacteria population doubles in size every day. Suppose a sample starts with 1000 bacteria. The expression 1000 · 2x models the number of bacteria in the sample after x days. Evaluate the expression for x = 0, 2, 5.

Answer 1

x=0, 0 bacteria

x=2, 4000 bacteria

x=5, 10000 bacteria

Explanation:

For this question, all we have to do is input the x values into the expression in order to get the number of bacteria for each given x-days.

So for example if x=0 then we input it as 1000x2(0) which equals 0
