Answer

Final Answer: The vertex of the parabola is at the point (1,2), the focus is at the point (1,0), the directrix is the line y=4, and the axis of symmetry is the vertical line x=1

Steps

Step 1 :The given equation is in the form of 4p(yk)=(xh)2, which is the standard form of a parabola that opens upwards or downwards.

Step 2 :Here, h=1, k=2 and 4p=8, so p=2.

Step 3 :The vertex of the parabola is at the point (h,k), the focus is at the point (h,k+p), and the directrix is the line y=kp. The axis of symmetry is the vertical line x=h.

Step 4 :Substituting the values of h, k, and p into the formulas, we get the vertex at the point (1,2), the focus at the point (1,0), the directrix at the line y=4, and the axis of symmetry at the vertical line x=1.

Step 5 :Final Answer: The vertex of the parabola is at the point (1,2), the focus is at the point (1,0), the directrix is the line y=4, and the axis of symmetry is the vertical line x=1
