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 the calculation to treat of the first f'(x) = -x + 4 = 0 giving x = 4f(4) = -8 + 16 - 11 = 8 -11 = -3 so it might be this one - Oh, no, since the coefficient of x is negative you have a maximum of valuethe right, either C or D Have made the calculation?
