Step 1 :
\The parabola equation is .
Write the equation in a translated form of a parabola .
Where is the vertex of the parabola,
p is the directed distance from vertex to focus,
\Focus is , and
Equation of the directrix is .
Step 2 :
\The parabola equation is .
Compare the above equation with translated form of a parabola .
Vertex .
.
Focus is :
.
Equation of the directrix :
\Vertex is , focus is
, and directrix is
.
Step 3 :
\The parabola is .
Vertex is , focus is
, and directrix is
.
Make the table of values to find ordered pairs that satisfy the equation.
\Choose values for x and find the corresponding values for y.

Step 4 :
\1. Draw a coordinate plane.
\2. Plot the vertex and focus of the parabola.
\3. Plot the ordered pairs found in the table.
\4. Connect those plotted points with a smooth curve.
\Solution :
\Vertex is , focus is
, and directrix is
.
