Hello friends,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to understand Concavity, But I've some doubts. As we know quadratic polynomial on graphing forms a parabola opening upwards or downwards. While understanding concavity we divide graphs into separate region using inflection points and each separate region is a quadratic polynomial in its own. So, its derivative should be linear. Then why the derivative of function ' f ' in the domain (vertical green line) is not linear.
