    not 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 \((-4,\infty)\)

    @satellite73 is there any relative extrema here?
