Best ResponseYou've already chosen the best response.1not to butt in, but you certainly don't need calculus for this it is a quadratic, therefore a parabola the leading coefficient is positive, so it open up the first coordinate of the vertex is \(4\) so it decrease on \((\infty, 4)\) and increases on \((4,\infty)\)
