In this video, you'll learn how to work with quadratic functions written in vertex form, y=a(x-h)²+k, and how this form helps you quickly identify key featur...

The vertex form of a quadratic function is given by f ( x ) = a ( x - h ) 2 + k , where ( h, k ) is the vertex of the parabola. Remember: the "vertex? is the "turning point".

Students will use vertex form to graph quadratic equations and describe transformations from the parent function with 70% accuracy. If a parabola opens upward, it has a lowest point. If a parabola opens downward, it has a highest point. This lowest or highest point is the vertex of the parabola.

a) Calculate the vertex (show work for the problems that are in Standard Form #1-5) b) Record the vertex in the blank provided. Make sure to write it as an ordered pair.

Feb 18, 2019 · Recall the standard form of a quadratic equation. There is another form of the quadratic equation called vertex form. Ø (h, ) is the vertex of the graph. Ø determines if the graph opens up or down. Ø also determines if the parabola is vertically compressed or stretched.

3 days ago · Recognizing Characteristics of Parabolas. The graph of a quadratic function is a U-shaped curve called a parabola.One important feature of the graph is that it has an extreme point, called the vertex.If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point ...

Example 1 Graph a Quadratic Equation in Vertex Form Analyze y = (x – 3)2 – 2. Then draw its graph. This function can be rewritten as y = [x – (3)]2 – 2. Then h = 3 and k = –2. The vertex is at (h, k) or (3, –2), and the axis of symmetry is x = 3. The graph has the same shape as the graph of y = x2 translated 3 units right and 2 units down.

Examples, videos, and solutions to help Algebra I students learn how to graph simple quadratic equations of the form y = a (x-h) 2 + k (completed-square or vertex form), recognizing that (h, k) represents the vertex of the graph and use a graph to construct a …

recognizing that (ℎ, 𝑘) represents the vertex of the graph and use a graph to construct a quadratic equation in vertex form. Students understand the relationship between the leading coefficient of a quadratic function and its concavity
