I don't have the slightest idea how to find the turning points of this function; f(x) = 2/3X^3 - 1/2X^2 + 4
Could you please help me?
I'd appreciate it a lot
$\displaystyle x(2x-1)=0\rightarrow x=0\text{ or }\frac 12\Rightarrow y=4\text{ or }\frac 23\cdot\left(\frac 12\right)^3-\frac 12\cdot \left(\frac 12\right)^3+4\approx 3.958 $. So the points are: $\displaystyle (0|4)$, $\displaystyle \left(\frac 14|\approx 3.958\right)$.
