1. The problem statement, all variables and given/known data All you know about a function f[x] is: f=2, f '=6, and f ''=-8. Write down the expansion of f[x] in powers of x through the x^2 term 2. Relevant equations none 3. The attempt at a solution I think the answer is 2 + 6x - 4x^2 , I just don't have any way to check so I want someone to confirm this.
