Question: Let y 1 = x 2 and y 2 = 2 X . (a) Graph y 1 and y 2 in [-5, 5] by [-2,
Let y1 = x2 and y2 = 2X.
(a) Graph y1 and y2 in [-5, 5] by [-2, 10]. How many times do you think the two graphs cross?
(b) Compare the corresponding changes in y1 and y2 as x changes from 1 to 2, 2 to 3, and so on. How large must x be for the changes in y2 to overtake the changes in y1?
(c) Solve for x: x2 = 2X.
(d) Solve for x: x2 < 2X.
