Using function concepts, it is found that the turning points of the graph are:
- November 2000, when it goes from increasing to decreasing.
- December 2000, when it goes from decreasing to increasing.
- June 2001, when it goes from increasing to decreasing.
In a graph:
- A function is increasing if it is <u>pointing upwards.</u>
- If it is <u>pointing downwards,</u> it is decreasing.
- A turning point is when the function changes from <u>decreasing to increasing or vice-versa</u>.
In this problem:
- Initially, the function is increasing.
- In month 3, that is, November 2000, it starts to decrease, thus, in November 2000, we have a<u> turning point.</u>
- The next month, that is, December 2000, it starts to increase again, so it is another <u>turning point</u>.
- It increases until month 9, which is June 2001, when it starts to decrease, being the <u>final turning point.</u>

Answer:
theres no photo
Step-by-step explanation:
Answer:
110d + 80 > 1620
d > 14
Step-by-step explanation:
The amount of points from collecting diamonds can be represented by 110d, since you get 110 points for each diamond, d
Add 80 to this to represent the bonus points.
Use a greater than inequality, because you have to get more than 1620 points.
Put this all together:
110d + 80 > 1620
Then, solve for d:
110d + 80 > 1620
110d > 1540
d > 14
So, you have to collect more than 14 diamonds in less than 2 minutes in order to advance to the next level.
Answer:
y = 9
Step-by-step explanation:
We notice that both points have a y-coordinate of 9. Since they are the same, the equation must be y = 9 because the function can't "dip" or "rise", otherwise it would be a piecewise function and not a linear function. The equation y = 9 basically means that no matter what x is, y will always be 9.
