(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The function f is defined as

f(x)=3x^5-10x^3+1

1) Determine the maximum and minimum points, as well the point of inflection of the graph f.

2. Relevant equations

All the differentiation equation.

3. The attempt at a solution

I found the maximum point and minimum point, but I had some trouble with the inflection point.

So....

f''(x)=60x^3-60x^2

f''(x)=0,

60x^3-60x^2=0

x=0, x=1

f'''(0)=0

Hence the only inflection point is (1,-6)

But the answer given is (0,1),(1,-6)and (-1,8). Is the answer correct?
