Best ResponseYou've already chosen the best response.0Are you supposed to use calculus to figure out the problem? If so, it's a lot less tedious.

Best ResponseYou've already chosen the best response.0Based on the intercepts, you know your equation factors down into (x3)(x7). Multiplying it out gives x^2  10x + 21. Your parabola also has a minimum at halfway between your intercepts, by reflection, at x = 5. Plugging in 5 above gives 4, but we want 2, so we can multiply the equation by 1/2. y = (1/2)*(x^2  10x + 21)
