How do you know if a turning point is maximum or minimum?
How do you know if a turning point is maximum or minimum? To work out which is the minimum and maximum, differentiate again to find f''(x). Input the x value for each turning point. If f''(x) > 0 the point is a minimum, and if f''(x) < 0, it is a maximum. What is a minimum turning point? A minimum turning point is a stationary point that has a gradient of 0 and has a negative gradient on the left side of the stationary point and a positive gradient on the right side of the stationary point.
