Answer:
Simple.
The decimal 0.5555 is a rational number. It's a terminating decimal, since it doesn't end with an ellipsis.
ANSWER
![y= {(x+ 1)}^{2}](https://tex.z-dn.net/?f=y%3D%20%20%7B%28x%2B%201%29%7D%5E%7B2%7D)
EXPLANATION
The given points are:
(1, 4), (2, 9), and (3, 16)
It is obvious that the function is not linear because there is no constant difference among the y-values.
We can however manipulate the y-values to quickly identify the function.
![4 = {2}^{2} = {(1 + 1)}^{2}](https://tex.z-dn.net/?f=4%20%3D%20%20%7B2%7D%5E%7B2%7D%20%20%3D%20%20%7B%281%20%2B%201%29%7D%5E%7B2%7D%20)
![9= {3}^{2} = {(2 + 1)}^{2}](https://tex.z-dn.net/?f=9%3D%20%20%7B3%7D%5E%7B2%7D%20%20%3D%20%20%7B%282%20%2B%201%29%7D%5E%7B2%7D%20)
![16= {4}^{2} = {(3 + 1)}^{2}](https://tex.z-dn.net/?f=16%3D%20%20%7B4%7D%5E%7B2%7D%20%20%3D%20%20%7B%283%20%2B%201%29%7D%5E%7B2%7D%20)
We can infer from the pattern that, the function is;
![y= {(x+ 1)}^{2}](https://tex.z-dn.net/?f=y%3D%20%20%7B%28x%2B%201%29%7D%5E%7B2%7D%20)
Answer: ![x=-5, -3](https://tex.z-dn.net/?f=x%3D-5%2C%20-3)
Step-by-step explanation:
![x^2 +8x+15=0\\\\(x+5)(x+3)=0\\\\x=-5, -3](https://tex.z-dn.net/?f=x%5E2%20%2B8x%2B15%3D0%5C%5C%5C%5C%28x%2B5%29%28x%2B3%29%3D0%5C%5C%5C%5Cx%3D-5%2C%20-3)
