If a person has contracts a bacteria, and each bacteria divides every 20 minutes, how many will they have after 40 hours?

The example they gave is this:
20 min: 2
40 min: 4
80 min: 8
etc.

I can't think of a way to do this without a long and very painful process, so please show me your work for it! Thanks!

hello i got a math homework sheet and the following question appears:

the relation that is NOT a function is:

a) y = √x +2
b) y = -3/x
c) y= 2/x^2
d) x^2 + y^2 = 36

i know that a function is where x can only have one unrepeating value to it but i dont understand how to do this question

help will be very appreciated thanks alot
