If it's negative - concave down. Solution: Since this is never zero, there are not points ofinflection. The relative extremes (maxima, minima and inflection points) can be the points that make the first derivative of the function equal to zero:These points will be the candidates to be a maximum, a minimum, an inflection point, but to do so, they must meet a second condition, which is what I indicate in the next section.
