Exercise 16 Page 494

We are asked to solve the given quadratic equation by graphing. There are three steps to solving a quadratic equation by graphing.

1. Write the equation in standard form, $a{x}^2+bx+c=0.$
2. Graph the related function $y=a{x}^2+bx+c.$
3. Find the $x\text{-}$intercepts, if any.

The solutions of $a{x}^2+bx+c=0$ are the $x\text{-}$intercepts of the graph of $y=a{x}^2+bx+c.$ Our equation is already written in standard form. Let's identify the function related to the equation.

Graphing the Related Function

To draw the graph of the related function written in standard form, we must start by identifying the values of $a,$ $b,$ and $c.$
