C1 Graph Question watch

1. Hello, my friend is stuck on a question and my knowledge of C1 has evaporated, could you give any tips on how to solve?

Figure 1 show the curve with equation y=f(x ) which crosses the x axis at the origin and the points A and B.

(a) given that f'(x )= 6-4x-3x^2 find an expression for y in terms of x.
(b) show that AB= k root 7 where k is an integer to be found.

All help would be appreciated.

i). Integrate f'(x).
Determine the constant of integration by finding a point that the curve passes through.

ii) Factorise your f(x) and find the roots. Then AB is just the largest - smallest.

"How would you find the point that the curve passes through, or is it just (0,0)?"
