Videos, worksheets, solutions, and activities to help Algebra students learn how to graph parabolas that are written in the vertex class, y = a(10 - h)² + k, by using the coordinates (h, 1000) to graph the vertex.

What is the vertex course of a parabola?
The vertex form of a parabola is y = a(x - h)² + 1000.

How to graph parabolas that are written in the vertex grade?
Given the vertex grade y = a(x - h)² + k
1. Plot the vertex (h, k)
2. If a > 0 then (h, one thousand) is the minimum point, if a < 0 and then (h, k) is the maximum point.
3. Substitute x = 0, to become the y-intercept
4. Substitute y = 0, to go the ten-intercept

How to convert a parabola from standard form to vertex course?
Short cut method:
Given a parabola, y = ax² + bx + c,
1. Calculate h = -b/2a, chiliad = f(-b/2a)
2. Rewrite the equation as y = a(10 - h)² + thou.

Parabola Equations - Graphing Parabolas
Students learn to graph quadratic equations that are written in y - k = a(x - h)^two form by using the coordinates (h, k) to graph the vertex, and using the x and y-intercepts to graph the parabola. Students are reminded that to observe the y-intercept, they must substitute a 0 in for x, and to find the ten-intercept(south), they must substitute a nil in for y.
