Does the parabola y = 3x^2 + 2x  1 have a maximum or minimum value?

(1) Find out if it has a Stationary Point.
Take the derivative of y.
Solve for x when the derivative is 0.
(2) If it does, determine their status as maxima, minima, or inflection(s).
Inspect the values of the curve slightly before and after the point(s).
