Find the local extreme points and inflection points of $y=2x^3 + 3x^2 - 12x.$
I know how to find the extreme points, but am confused on the inflection points. We use the second derivative to found those right?

Hint: Where the second derivative is equal to zero or undefined.
Here we have $$f''(x) = 12 x + 6 = 0$$
Can you take it from here?
You should have also found a local minimum at $x=1$ and a local maximum at $x=-2$.
