The graph of which function has a minimum located at (4, –3)? f(x) = -1/2x2 + 4x – 11 f(x) = –2x2 + 16x – 35 f(x) =1/2x2 – 4x + 5 f(x) = 2x2 – 16x + 35

You can use calculus to do this  

try the first one 
f'(x) = -x + 4 = 0   giving x = 4
f(4) = -8 + 16 - 11 = 8 -11 = -3   so it could be this one 
- Oh no since the coefficient of x is negative it will have a maximum value

the correct one will be either C or D 

Have you done any calculus?
