A long jumper left the ground at an angle of 15 degrees and jumped a distance of 7.0m. Considering this result, calculate the velocity of the long jumper leaving the ground.

The point (1.6) lies on the curve y=f(x). If f''(x) = 12(x-1)^2, determine whether (1,6) is a point of inflexion or not.
Subbing in 1 gives 0 for the 2nd derivative but the answer says it isn't a pt of inflexion ?_?...
I remember when we had an info night for subject choices and the deputy principals said that scaling won't have any effect and then the next day our careers advisor just said"bullshit, it matters." lol.
