This is the next simplest type of function after the linear function. What is the vertex? The vertex occurs halfway between the x-intercepts -1 and 3, so at x = 1. A quadratic function is a second-degree polynomial function of the form. Students will represent functions in a variety of forms, identify the domain and range of functions, and investigate the behavior of graphs of functions. For which values of b will the quadratic function f(x) = x2 − 2bx + 7 have a minimum value of 6? 2. Never runs out of questions. If the equation has just one solution (a repeated root) then the graph just touches the x-axis without crossing it. Key Takeaways. ©6 xKruht1aG 4SVoDfet1wyaOrceZ GLPLXCZ.

Exploration 1 is in three mains parts. The most natural quadratic form to associate with a graph is the Laplacian , which is given by xTL Gx = # (a,b)∈E w(a,b)(x(a) −x(b))2. If the graph touches the x-axis at one point the quadratic has 1 repeated root. the graph of the function is zero at that point, but the curve of the graph is concave down. In a parabola that opens downward, the vertex is the maximum point. !!2 determines if the graph opens up or down. The graph of any quadratic equation y = a x 2 + b x + c, where a, b, and c are real numbers and a ≠ 0, is called a parabola. Parabola : The graph of a quadratic function is a parabola.
