Find the local maxima and minima, and all the inflection points, of
y= 9x^4 − 11x^3 + 3x^2 + 1
how would i start off by doing this question? thank u
x-coordinates of local maxima and minima: Solve . Use the double derivative test (or the sign test) to determine the nature of the stationary points.
If you want NON-stationary points of inflection as well, solve . Points of inflection for y occur where has either a maximum or a minimum turning point.
