Answer:
Please see below.
Step-by-step explanation:
f(x) is a quadratic polynomial. Its two roots are given: x=2, and x=4.
This means that
![f(x) = 0 = d\cdot(x-2)\cdot(x-4) = d\cdot(x^2-6x+8)](https://tex.z-dn.net/?f=f%28x%29%20%3D%200%20%3D%20d%5Ccdot%28x-2%29%5Ccdot%28x-4%29%20%3D%20d%5Ccdot%28x%5E2-6x%2B8%29)
with d some unknown constant that stretches the parabola along the y axis. Since we are also given f(1), d can be determined:
![f(x) = d\cdot(x^2-6x+8)\\f(1)=3d=6\implies d=2\\\mbox{so}\\f(x) = 2\cdot(x^2-6x+8)=2x^2-12x+16\\\mbox{so}\\a=2, b=-12, c=16](https://tex.z-dn.net/?f=f%28x%29%20%3D%20d%5Ccdot%28x%5E2-6x%2B8%29%5C%5Cf%281%29%3D3d%3D6%5Cimplies%20d%3D2%5C%5C%5Cmbox%7Bso%7D%5C%5Cf%28x%29%20%3D%202%5Ccdot%28x%5E2-6x%2B8%29%3D2x%5E2-12x%2B16%5C%5C%5Cmbox%7Bso%7D%5C%5Ca%3D2%2C%20b%3D-12%2C%20c%3D16)
