Mark raises guppies in an aquarium. He finds out that guppies reproduce very rapidly, and the number quadruples every month. He
starts out with only 2 guppies, and the function y equals 2 times 4 to the x models the number of guppies he will have after x months. Which graph represents this function?
1 answer:
For this case what we should know is that the function that best adapts to this problem is given by:
y = 2 * (4) ^ x
The graph of the function is shown for two different intervals:
A small interval of -1.5 to 0.5
A larger interval of -6.5 to 6.5.
In both intervals the exponential growth of the function is demonstrated.

1) In this problem, the first thing to do is to enlist the categories:
workers time to clean # apartments
8 2h15 12
8 9 x
2) Note that the number of cleaners is the same. So, we can pick the ratios that fall under the category <em>time </em>and <em>#apartments</em>
<em />
We need to convert that 2h 15 into decimal form before setting the ratios:
3) Now, we can set the ratios and solve for x:
Thus, the answer is 48
