1. The maximum value attained by the function$$ f(x)=x(x-1)(x-2)$$ in the interval f[1, 2] is :——– Solution: $$ f(x)=x(x-1)(x-2)$$ $$\Rightarrow f(x)=x^3-3x^2+2$$ $$\Rightarrow f^1(x)=3x^2-6x+2=0 $$ $$ \Rightarrow x=1\pm \frac{1}{\sqrt 3} $$ But $$ x=1+\frac{1}{\sqrt 3} $$ only lies on the interval … Continue reading
