Step-by-step explanation:
<u>Consider the parent function:</u>
The graph of the function open up and the vertex is at the origin, the point (0, 0)
Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:
The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:
<u>Since all the options have 1/20 as a coefficient, our function is:</u>
This is option B
Answer:
B is the correct answer to your question
2nd attempt carries a price of 6% extra, so (6/100) * 548 is 32.88, so 548 + 32.88, the price is 580.88.
for the 3rd attempt 6% extra of that, (6/100) * 580.88, is 34.8528, so the price is 615.7328.
4th attempt is 6% extra of that, (6/100) * 615.7328, 36.943968, adding that will give us 652.676768.
![y = 2 {x}^{3} - 7 {x}^{2} + 2x + 3](https://tex.z-dn.net/?f=y%20%3D%202%20%7Bx%7D%5E%7B3%7D%20%20-%207%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20%2B%203)
By inspection 1 is a root of y ,
Hence , (x-1) is a factor of y ,
![\dfrac{2 {x}^{3} - 7 {x}^{2} + 2x + 3 }{x - 1} = 2 {x}^{2} - 5x - 3 \\ \\ 2 {x}^{2} - 5x - 3 = (2x + 1)(x - 3)](https://tex.z-dn.net/?f=%20%5Cdfrac%7B2%20%7Bx%7D%5E%7B3%7D%20-%207%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20%2B%203%20%7D%7Bx%20-%201%7D%20%20%3D%202%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20-%203%20%5C%5C%20%20%5C%5C%202%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20-%203%20%3D%20%282x%20%2B%201%29%28x%20-%203%29)
Hence , the 2 other roots are -1/2 and 3 , and the above graphs confirms the same.
Hope it helps you :)
