Which of the following x and y intervals would describe a good window for the graph of f(x) = 0.1x^3 - 4x^2 + 35x - 80?
-10 < x < 10; -10 < y < 10
-20 < x < 20; -20 < y < 20
-20 < x < 30; -20 < y < 20
-10 < x < 30; -200 < y < 20 <- this is what i think it is
-10 < x < 10; -10 < y < 10
-20 < x < 20; -20 < y < 20
-20 < x < 30; -20 < y < 20
-10 < x < 30; -200 < y < 20 <- this is what i think it is
