Answer: a. ![g(x)=x^2-2x-8](https://tex.z-dn.net/?f=g%28x%29%3Dx%5E2-2x-8)
Step-by-step explanation:
You know that the zeros of the function g(x) are:
![x=-2\\x=4](https://tex.z-dn.net/?f=x%3D-2%5C%5Cx%3D4)
Then, the factored form must be:
![(x+2)(x-4)=0](https://tex.z-dn.net/?f=%28x%2B2%29%28x-4%29%3D0)
Now, applying the Distributive property:
![(x+2)(x-4)=0\\\\(x)(x)+(x)(2)+(x)(-4)+(2)(-4)=0\\\\x^2+2x-4x-8=0](https://tex.z-dn.net/?f=%28x%2B2%29%28x-4%29%3D0%5C%5C%5C%5C%28x%29%28x%29%2B%28x%29%282%29%2B%28x%29%28-4%29%2B%282%29%28-4%29%3D0%5C%5C%5C%5Cx%5E2%2B2x-4x-8%3D0)
Finally, adding the like terms, you get:
![x^2-2x-8=0](https://tex.z-dn.net/?f=x%5E2-2x-8%3D0)
Therefore, the function g(x) is:
![g(x)=x^2-2x-8](https://tex.z-dn.net/?f=g%28x%29%3Dx%5E2-2x-8)
Answer:
y=-1/2x
Step-by-step explanation:
y-(-2)=-1/2(x-4)
y+2=-1/2x+2
y=-1/2x
