The point of inflection for π(π₯)=3π₯4−4π₯3 are
- A.
x=1 and x=2
- B.
x=0 and x=2/3
- C.
x=3 and x=-1
(Correct Answer) - D.
x=4/5 and x=-1
Correct Answer: x=3 and x=-1
Explanation
If the function was actually f(x)=x3β3x2β9x, then the first derivative would be:
Setting this to zero:
This gives the answers x=3 and x=β1. These would be the points where the graph has local maxima or minima.
