What do the graphs f(x) = (x + 5)(x - 1), g(x) = 0.8(x + 5)(x - 1), and h(x) = -3(x + 5)(x - 1) all have in common? These functions are in the same ___________ of polynomial functions. Ex: What family of equations has zeros at -3, 0, 2/3, and 1? What is the value of a if the graph passes through (-1, 4)?
