Given g(x)=x^2-7x+1/4 show that the least possible value of g(x) is -12

nadezda [96]

$\displaystyle\\
g(x)=x^2-7x+\frac{1}{4} \\ \\ 
g(x)=x^2-7x+0.25\\ \\ \\ \\ 
x \text{ for } g_{min} = \frac{-b}{2a}=\frac{-(-7)}{2\times 1}= \frac{7}{2}=3.5 \\ \\ 
g_{min} = g(3.5) = (3.5)^2 -7\times 3.5 + 0.25= 12.25 - 24.5 +0.25 = \boxed{-12}$
