Oct 19 2024 0183 32 The easiest way to find the vertex is to use the vertex formula If your equation is in the form ax 2 bx c y you can find the x value of the vertex by using the formula x b 2a So if you re working with the equation 2x 2 4x 9 y a 2 b 4 and c 9
A quadratic function can be graphed using a table of values The graph creates a parabola The parabola contains specific points the vertex and up to two zeros or x intercepts The zeros are the points where the parabola crosses the x axis If the coefficient of the squared term is positive the parabola opens up Given a quadratic function find the domain and range Identify the domain of any quadratic function as all real numbers Determine whether latex a latex is positive or negative
Remember to find the zeros of a function simply set the function equal to zero and solve Setting a quadratic function equal to zero and solving means you re solving a quadratic equation so you can solve by factoring solve by completing the square or solve by using the quadratic formula
