Question

Junior removes the drain plug from his pool.

Answer 1

Answer:

Shown in the Figure below

Step-by-step explanation:

To know if a table represents a exponential function, we must choose each value of the independent variable and divide it by the next value. If each division results in the same value called the ratio, we can assure that this is an exponential function. So the only options that meet this requirement are the options shown below because:

$\frac{3300}{2100}=\frac{10}{7} \\ \\ \frac{2100}{1470}=\frac{10}{7} \\ \\ \frac{1470}{1029}=\frac{10}{7}$

and:

$\frac{2400}{1920}=\frac{5}{4} \\ \\ \frac{1920}{1536}=\frac{5}{4} \\ \\ \frac{1536}{1228.80}=\frac{5}{4}$

So the other options doesn't meet this requirement.
