**drwls**, Saturday, November 7, 2009 at 5:16amSet the derivative f'(x) = 0 and solve for x.

-6x + 7 = 0

x = 7/6

Since the second derivative f"(x) = -6, the extremum at x = 7/6 is a maximum. The minimum for the interval [1,3] will occur at x = 3, since the f(x) just keeps getting lower for higher values of x when x > 7/6.
