[B] The graph widens
[C] The graph narrows
[D] The vertex moves down the y axis.

Question2: The path of a basketball thrown at an angle of 450 can be modeled by y = -0.02x2 +x + 6

Question3: Write three different quadratic functions whose graphs have the line x = 4 as an axis of symmetry but have different y-intercepts

Question4: The path of a shot put released at an angle of 450 can be modeled by y = -0.01x2 + 0.7x + 6
