For the second derivative I got f(x)=6x-16 and then got x=16/6 when set to zero.

**Damon**, Wednesday, October 24, 2012 at 1:35pm3 x^2 -16 x + 5 = 0

first derivative

at x = {16 +/-sqrt(256-60)]/6

or [16+/-14]/6 = 5 or 0.3333

second derivative

6 x - 16

is that + or - at the two points where the slope is zero?

at x = .333

2 - 16 is negative so maximum there

at x = 5

6x - 16 = 30-16 is positive so minimum there
