Years 7. A colony of E. Coli in a lab doubles in number every 20 minutes through cell division. How many
*HOURS* would it take for 1 cell of E. Coli to become 100 cells in a petri dish?

answer is 20 hrs hope it helps

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
