a family swimming pool holds 60m2 of water. the function below gives the cubic
meters of water in the pool, taking into account water lost to evaporation over x
days. how much water does the pool have after 7 days?
f(0) = 60 - 0.187

58.74 cubic meters

Step-by-step explanation:

The function is actually  

Here x is the number of days and the corresponding value of "f(x)" would be the water REMAINING after x days.

Since, we want to figure out how much water (from 60 m^3) is remaining after 7 days, we simply have to plug in x = 7 into the function. Whatever number we get, is the AMOUNT OF WATER REMAINING AFTER 7 DAYS.

So,

Thus, the amount of water remaining in the pool after 7 days is 58.74 cubic meters

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
