**Reiny**, Monday, October 15, 2012 at 11:04pmf ' (3) = 0 tells me that at the point (3,5) the tangent is horizontal, so (3,5) must be either a maximum or a minimum.

f '' (3) = 3 tell sme that at the point (3,5) the curve is concave up, so

(3,5) must be a minimum point.

(it couldn't possibly be a point of inflection or else the f '' (3) would have been 0 )
