Final answer:
The focus of the parabola is (0, 3) and the directrix is the line y = -3.
Step-by-step explanation:
The equation y = 1/12x^2 represents a parabola. To find the focus and directrix of the parabola, we can use the vertex form of the equation: y = a(x-h)^2 + k, where (h, k) is the vertex of the parabola.
In this case, a = 1/12. The vertex is located at (h, k) = (0, 0). The focus is a point inside the parabola, and it is located at a distance equal to 1/4a units above the vertex. Therefore, the focus of the parabola is (0, 1/(4a)) = (0, 3).
The directrix of the parabola is a horizontal line that is a distance equal to 1/4a units below the vertex. Therefore, the directrix of the parabola is the line y = -1/(4a) = -3.
