## Homework Equations

Equations are located in the above img.

## The Attempt at a Solution

I first integrated the first derivative and got -

(ax^3)/3 + (bx^2)/2

plugged in 1 and got -

6=a + b

Then I got the second derivative --> 2ax +b and plugged in f''(1) and got: 18 = 2a +b

Using both the equations, I figured out that:

a=12

b=-6

how do I find the contant c to get f(x)?-Jennie
