Answer:
I could only find a single semi-complete question on that paper due to the quality of the picture. <u>The carbon dioxide and water escape from the tube, because as gases, they do not have a definite shape or volume, and instead expand to fit whatever container they are in.</u>
Hope it helps
1. The x-intercepts are x = 0 and x = 6. You can find these by looking for where the line crosses the x-axis. You can see here that it does so at 0 and 6.
2. The maximum value for this function is looking for the f(x) value at the highest point. In this case, you will see that f(x) at the highest point is 120. This happens at x = 3. Once again, this can be found just by looking for the highest point on the graph.
3. Since that is the absolute highest point, it is also the point where is goes from increasing to decreasing. As a result, we know the increasing interval is x<120 and the decreasing interval is x > 120.
4. Finally, the average rate of change between 3 and 5 is -30. You can find this by determining the amount of change in f(x) and dividing it by the amount of change in x. The basic formula is below.



-30
First leave the first fraction alone.
Then turn the division sign into a multiplication sign.
Flip the second fraction over ( find its reciprocal ).
Multiply the numerators of the two fractions together. This result will be the numerator ( the top part ) of your answer.
Multiply the denominators of the two fractions together. The result will be the denominator ( the bottom part ) of your answer.
Then simplify your fraction by reducing it to the simplest terms.
