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 $\"\"$ .

\

$\"\"$

\

To change the expression into a perfect square trinomial add $\"\"$ to each side of the equation.

\

The x coefficient 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 4 :

\

\

\

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.

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

\ x \	\ $\"\"$ \	\ $\"\"$ \
\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \
\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \
\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \
\ 0 \	\ $\"\"$ \	\ $\"\"$ \
\ 2 \	\ $\"\"$ \	\ $\"\"$ \
3	\ $\"\"$ \	\ $\"\"$ \

\

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.
