A particular type of cell doubles in number every hour. Which function can be used to find the number of cells present at the end of h hours if there are initially 4 of these cells

a) n=4(1/2)^h
b) n=4(2)^h
c) n=4+(2)^h
d) n=4+(1/2)^h

Using the correct answer (b) determine how many cells will be present in 6 hours

The correct function to represent the number of cells present at the end of h hours is:

n = 4(2)^h

To find how many cells will be present in 6 hours, substitute h = 6 into the function:

n = 4(2)^6
n = 4(64)
n = 256

Therefore, there will be 256 cells present after 6 hours.
