First day : 30+20y
Second day : 85 + 17y
Total: 30 + 20y + 85 + 17y This is the not simplified version.
37y+115 This is the simplified version.
A Turning Point where a local maximum or local minimum happens.
The given function is ⇒⇒⇒ <span>y = x³ – 3x + 3
</span>
The graph of the given function is as shown in the attached figure.
So, The turning
points of function are (–1, 5) and (1, 1)
Answer:
![320x^{15}](https://tex.z-dn.net/?f=320x%5E%7B15%7D)
Step-by-step explanation:
1. take out constants
( 5 × 2 × 4 × - 4 × - 2) ![x^{5} x^{5} x^{5}](https://tex.z-dn.net/?f=x%5E%7B5%7D%20x%5E%7B5%7D%20x%5E%7B5%7D)
2. simplify 5 × 2 to 10
(10 × 4 - 4 × - 2)![x^{5} x^{5} x^{5}](https://tex.z-dn.net/?f=x%5E%7B5%7D%20x%5E%7B5%7D%20x%5E%7B5%7D)
3. simplify 10 × 4 to 40
(40 × - 4 × - 2)![x^{5} x^{5} x^{5}](https://tex.z-dn.net/?f=x%5E%7B5%7D%20x%5E%7B5%7D%20x%5E%7B5%7D)
4. simplify 40 × -4 to -160
(-160 × - 2)![x^{5} x^{5} x^{5}](https://tex.z-dn.net/?f=x%5E%7B5%7D%20x%5E%7B5%7D%20x%5E%7B5%7D)
5. simplify -160 × -2 to 320
![320x^{5} x^{5} x^{5}](https://tex.z-dn.net/?f=320x%5E%7B5%7D%20x%5E%7B5%7D%20x%5E%7B5%7D)
6. use product rule:![x^{a} x^{b} =x^{a+b}](https://tex.z-dn.net/?f=x%5E%7Ba%7D%20x%5E%7Bb%7D%20%3Dx%5E%7Ba%2Bb%7D)
![320x^{5+5+5}](https://tex.z-dn.net/?f=320x%5E%7B5%2B5%2B5%7D)
7. simplify 5 + 5 to 10
![320x^{10+5}](https://tex.z-dn.net/?f=320x%5E%7B10%2B5%7D)
8. simplify 10 + 5 to 15 ![320x^{15}](https://tex.z-dn.net/?f=320x%5E%7B15%7D)
