Question 601469
{{{f(x)= -4x^2+12x-9}}}



{{{f(1/2)= -4(1/2)^2+12(1/2)-9}}}



{{{f(1/2)= -4(1/4)+12(1/2)-9}}}



{{{f(1/2)= -4/4+12/2-9}}}



{{{f(1/2)= -1+6-9}}}



{{{f(1/2)= -4}}}

-------------------------------------------------------


{{{g(x) = -9-3x+x^2}}}



{{{g(2) = -9-3(2)+(2)^2}}}



{{{g(2) = -9-3(2)+4}}}



{{{g(2) = -9-6+4}}}



{{{g(2) = -11}}}


-------------------------------------------------------


{{{6*f(1/2) - 2*g(2)}}}



{{{6*(-4) - 2*(-11)}}}



{{{-24 + 22}}}



{{{-2}}}



So {{{6*f(1/2) - 2*g(2)=-2}}}
