Answer:
The answer is:
Step-by-step explanation:
The equation of a parabola in the intercept form is given by:
![y=a(x-p)(x-q)](https://tex.z-dn.net/?f=y%3Da%28x-p%29%28x-q%29)
Where:
p and q are x-intercepts
Now, we know the parabola intercepts at x=1 and x=3.
So we will have:
![y=a(x-1)(x-3)](https://tex.z-dn.net/?f=y%3Da%28x-1%29%28x-3%29)
Using the point (-1,16) we could find the value of a.
![16=a(-1-1)(-1-3)](https://tex.z-dn.net/?f=16%3Da%28-1-1%29%28-1-3%29)
![16=8a](https://tex.z-dn.net/?f=16%3D8a)
![a=2](https://tex.z-dn.net/?f=a%3D2)
Therefore, the equation is:
![y=2(x-1)(x-3)](https://tex.z-dn.net/?f=y%3D2%28x-1%29%28x-3%29)
![y=2(x^{2}-4x+3)](https://tex.z-dn.net/?f=y%3D2%28x%5E%7B2%7D-4x%2B3%29)
![y=2x^{2}-8x+6](https://tex.z-dn.net/?f=y%3D2x%5E%7B2%7D-8x%2B6)
<u>The answer is: </u>
I hope it helps you!
