we got a few examples in class but not understanding it at all
Can someone please show steps as I am having a hard time understanding. The position (in meters) of a particle is modeled by y=x^3-12.5x^2+51x-67.5, where xis in seconds. Find the max, min and point(s) of inflection.
This is just for study for exam coming up and says it could be worth up to 12 marks. Not understanding vry well the two
