Answer:
x-intercept : None
y-intercept : (0, -24)
Vertex : (4, -8)
Focus : (4, -33/4)
Axis of Symmetry : x = 4
Directrix : y = -31/4
Step-by-step explanation: Use the vertex form to determine the values of a, h, and k and use these values to find the direction the parabola opens, vertex, focus, axis of symmetry, and directrix.
