Answer:
Option A
Step-by-step explanation:
x-7>2
x>9
Therefore, A is correct since 9 isn't included in the solution set.
Answer:
B
Step-by-step explanation:
So we have the two functions:
![f(x)=-2x^2-5x+1\text{ and } h(x)=3(x+3)^2-11](https://tex.z-dn.net/?f=f%28x%29%3D-2x%5E2-5x%2B1%5Ctext%7B%20and%20%7D%20h%28x%29%3D3%28x%2B3%29%5E2-11)
And we want to find:
![h(f(-1))](https://tex.z-dn.net/?f=h%28f%28-1%29%29)
So, find f(-1) first. Substitute -1 into f(x):
![f(-1)=-2(-1)^2-5(-1)+1](https://tex.z-dn.net/?f=f%28-1%29%3D-2%28-1%29%5E2-5%28-1%29%2B1)
Square:
![f(-1)=-2(1)-5(-1)+1](https://tex.z-dn.net/?f=f%28-1%29%3D-2%281%29-5%28-1%29%2B1)
Multiply:
![f(-1)=-2+5+1](https://tex.z-dn.net/?f=f%28-1%29%3D-2%2B5%2B1)
Add:
![f(-1)=4](https://tex.z-dn.net/?f=f%28-1%29%3D4)
Now, substitute this into h(f(-1)):
![h(f(-1))=h(4)](https://tex.z-dn.net/?f=h%28f%28-1%29%29%3Dh%284%29)
So, substitute 4 into h(x):
![h(4)=3(4+3)^2-11](https://tex.z-dn.net/?f=h%284%29%3D3%284%2B3%29%5E2-11)
Add:
![h(4)=3(7)^2-11](https://tex.z-dn.net/?f=h%284%29%3D3%287%29%5E2-11)
Square:
![h(4)=3(49)-11](https://tex.z-dn.net/?f=h%284%29%3D3%2849%29-11)
Multiply:
![h(4)=147-11](https://tex.z-dn.net/?f=h%284%29%3D147-11)
Subtract:
![h(4)=136](https://tex.z-dn.net/?f=h%284%29%3D136)
So, our answer is B.
And we're done!
