The answer is C if im correct
Hopes it Helps!
Answer: B
Step-by-step explanation:
Answer:
Domain: 1,2,4,8
Range: 2,4,8
Step-by-step explanation:
The Domain is always the "X" or input. Range is always the "Y" or output. As you can see here, there are same numbers in the domain and range. You put that as one number. Therefore, the above numbers are the answer.
Answer:
a=6, b=-2
Step-by-step explanation:
We are to determine the values for a and b that would make the equality
true.
Given:
![4y(ay^2 -7y+b)=24y^3 -28y^2 -8y](https://tex.z-dn.net/?f=4y%28ay%5E2%20-7y%2Bb%29%3D24y%5E3%20-28y%5E2%20-8y)
First, we expand the Left Hand Side of the equality
![4y(ay^2 -7y+b)=24y^3 -28y^2 -8y\\4ay^3 -28y^2+4yb=24y^3 -28y^2 -8y](https://tex.z-dn.net/?f=4y%28ay%5E2%20-7y%2Bb%29%3D24y%5E3%20-28y%5E2%20-8y%5C%5C4ay%5E3%20-28y%5E2%2B4yb%3D24y%5E3%20-28y%5E2%20-8y)
Comparing coefficients of the same power:
![y^3: 4a=24\\y^2:-28=-28\\y: 4b=-8](https://tex.z-dn.net/?f=y%5E3%3A%204a%3D24%5C%5Cy%5E2%3A-28%3D-28%5C%5Cy%3A%204b%3D-8)
Therefore:
![a= 24 \div 4 =6\\b=-8 \div 4=-2\\a=6, b=-2](https://tex.z-dn.net/?f=a%3D%2024%20%5Cdiv%204%20%3D6%5C%5Cb%3D-8%20%5Cdiv%204%3D-2%5C%5Ca%3D6%2C%20b%3D-2)
