Question 187641
1.True or false: The function "f(x) = 4x" grows four times faster than the function "g(x) = x". Explain 
False.  It grows 4 times as fast, not 4 times faster.  4 times faster is 5 times as fast.

2.A cell divides into two identical copies every 4 minutes. How many cells will exist after 5 hours? 
5 hours = 300 minutes = 75 4 minute periods.
The number of cells will have doubled 75 times, so there will be 2^75 times the number at the start.
If you start with 1 cell (it wasn't specified), you'll have 2^75, or apx
