Question

Determinati numarul real m pentru care varful parabolei asociate functiei f:R->R,f(x)=-x patrat+3mx+1 are abscisa egala cu 3/2

Answer 1

x = -b / 2a

$\frac{-3m}{-2}= \frac{3}{2} \\ \frac{3m}{2}= \frac{3}{2} \\ =>m = \frac{ \frac{3}{2} }{ \frac{3}{2}}= \frac{3}{2}* \frac{2}{3} = \frac{6}{6} =1 \\ =>m=1$
