How do you find the inflections points for #g(x) = 3x^4 − 6x^3 + 4#?
1 Answer
Inflection points are points on the graph at which the concavity changes. To find them, we need to investigate concavity, and to do that we need the sign of the second derivative.
Obviously,
Investigating the sign of

Inflection points are points on the graph at which the concavity changes, so we'll need the
The inflection points are:
