M and K are both polynomial functions of a where M(x) = (x+3)(2x - 5) and K(x) = 3(x+3)(2x – 5).
1. How are the two functions alike? How are they different?
2. If a graphing window of -5 ≤ x ≤ 5 and -20≤ y ≤ 20 shows all intercepts of a graph of y = M(x),
what graphing window would show all intercepts of y = K(x)?
