Cancel the common factor of. Simplify the result. In Depth In. Step 2. Plug in. Rewrite the equation in vertex form. So the vertex is. Negate to get. Raising to any positive power yields. The directrix of a parabola is the horizontal line found by subtracting from the y-coordinate of the vertex if the parabola opens up or down. Factor out of.

.

Start with the given equation. Multiply by. So when , which gives us the point 2, Substitute the known values of , , and into the formula and simplify. So the second point to the left of the axis of symmetry is 0,-3 Jump to Top of Page Step 3 Reflecting the two points over the axis of symmetry: Now remember, the parabola is symmetrical about the axis of symmetry which is This means the y-value for which is one unit from the axis of symmetry is equal to the y-value of which is also one unit from the axis of symmetry. Algebra Examples Popular Problems. So the y-coordinate of the vertex is. Find the distance from the vertex to a focus of the parabola by using the following formula. The final answer is. Factor out of. Substitute the value of into the formula.
