What is the equation of the parabola?

y = −one twelfthx2 − 2
y = one twelfthx2 − 2
y = −one twelfthx2 + 2
y = one twelfthx2 + 2

The answer to your question is    y = 12x + 2 from the choices it could be the last one because it is not 1/12.

Step-by-step explanation:

Data

From the graph get the vertex and the focus.

Also from the graph, we know it is a vertical parabola.

Vertex = (0, 2)

Focus = (0, 5)

Directrix    y = -1

From this data, we know that p = 3. P is the distance from the vertex to the focus or to the directrix.

Substitution

                   y - k = 4p(x - h)

                   y - 2 = 4(3)(x - 0)

Simplification

                  y - 2 = 12x

Result

                  y = 12x + 2

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

the ten thousandths place is the 2. you round it up if, that number in whatever place is 5 or higher.
