Let f (x) =x^3+bx^2+c. Find all the values of b and c such that f has an inflection point and then determine its location.

Can anyone help me solve this equation, as required?

Solve

This is a linear equation involving *b* only and so should be solvable for all values of *b*. The cubic function itself should also have inflection points for all values of the constant *c* since this only determines the height of the curve relative to the *x*-axis, not its shape.
