Vertex Form: What Is It? How Do You Calculate It?

WebTo find the vertex of a quadratic function in factored form, we take the average of the zeros. So, for the quadratic in factored form. f (x) = a (x – r) (x – s) we calculate c = (r + s) / 2 to find the x-coordinate of the vertex. Then, we plug in x = c into the function f (x) to find the y-coordinate of the vertex (we’ll call it d). WebIf there is no equals sign, but it has a quadratic term, then it is a quadratic expression. x² - x - 5 is a quadratic expression. So are the following: a² + 8a - 6 g² - 16 If there is an equals sign, we call it a quadratic equation. An example is x² - 4x + 3 = 0 Another example of quadratic equation is 16t² - 8t = 3 and, x = y² and sweater characteristicsWebIn this digital activity, students will identify the zeros of the function by equations and graphs.
