# Find an equation of the parabola. Then find the focus and directrix.9. To determine

To Find: The equation of the parabola, focus and the directrix by using figure (1). Explanation

Given:

By referring the figure (1), we can find the value of vertex and point of the parabola,

Then the vertex is (0,0) and point of the parabola is (1,1) respectively.

Calculation:

By referring the figure (1) equation is to be,

y2=4px (1)

Substitute the value 1 for x and 1 for y in the equation (1).

12=4p×(1)1=4pp=14

Then, the focus of the graph is to be (p,0) .

Therefore, the focus of the parabola is (14,0)_

Compute the directrix of the parabola
