It is known that the parabola y = 4x2-11x-3. (I) find its axis of symmetry; (II) find the coordinates of its intersection with x-axis and y-axis

(1) From the known, a = 4, B = - 11, we can get − B2A = − 118 = 118, the symmetry axis of the parabola is x = 118; (II) let y = 0, we can get 4x2-11x-3 = 0, the solution is X1 = 3, X2 = - 14, the intersection coordinates of the parabola and the X axis are (3,0), (- 14,0), let x = 0, we can get y = - 3, the intersection coordinates of the parabola and the Y axis are (0, - 3)

What is the intersection coordinate of the parabola y = 4x * x-11x-3 and the Y axis?

X = 0 of the point of intersection with y axis, substituting y = - 3, so the point of intersection is (0, - 3)
