Quiz 8-1 graphing quadratic equations

A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. [1] There are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square..

What does the second coordinate of the vertex of the quadratic function. A(w), represent? the minimum width that can be used for the fencing. the maximum area that can be enclosed by the fencing. the width that gives the maximum area. the length that gives the maximum area. The quadratic formula: x = [-B +/- sqrt(B^2-4AC)] / (2A) The discriminant is B^2-4AC. Notice this is the portion of the formula inside the square root. If the discriminant = 0, then the formula degrades to x = -B/(2A). So, there is only one solution. If the discriminant is positive, then the square root creates a real number.

This is a formula, so if you can get the right numbers, you plug them into the formula and calculate the answer (s). We always have to start with a quadratic in standard form: ax^2+bx+c=0. Making one up, 3x^2+2x-5=0, we see a=3, b=2, c=-5. I teach my students to start with the discriminant, b^2-4ac.

_{Solution method 1: The graphical approach. It turns out graphs are really useful in studying the range of a function. Fortunately, we are pretty skilled at graphing quadratic functions. Here is the graph of y = f ( x) . Now it's clearly visible that y = 9 is not a possible output, since the graph never intersects the line y = 9 .Graphing and Vertex Form. When we graph a quadratic equation, we need a y variable as well as an x, so we use y = ax^2 + bx + c.
