Question

Suppose you need to drain your swimming pool, and you use a pump that can remove 700 gallons per hour. You can model this scenario with $y = -700x + 2800$, where $y$ is the number of gallons left in the pool after $x$ hours of pumping. Find the $x$ and $y$ intercepts of this equation, interpret their meaning and use them to sketch a graph of the linear model.

The graph gives the number of gallons of water in a small swimming pool after x hours. (a) Write a formula for f(x). (b) Interpret both the slope and the y-intercept. (c) Use the graph to estimate how much water was in the pool after 3 hours. Verify your answer by evaluating f(x).

00:01 Okay, so i see that you need help with this question.
00:03 And it says, the graph gives the number of gallons of water in a small swimming pool after x hours.
00:09 So it starts at 3 ,000 and it's gaining 1 ,000 gallons per minute.
00:16 So it would be y equals 1 ,000x plus 3 ,000.
00:22 And so that would be f of x.
00:29 And so that would be f of x.
00:32 And you're going to put that here...
