You will be able to solve quadratic equations by graphing.
You will be able to estimate solutions of quadratic equations by graphing.
Today’s Objectives:
4.2 Solving Quadratics with Graphing
A general quadratic function is…
The standard form of a quadratic equation is…
SolutionsThe solutions of a quadratic are called roots of the equation.
The roots are the x-intercepts of its graph. Sometimes referred to as zeros because at those points the y is a zero.
Estimating RootsOften exact roots (whole numbers) cannot be found by graphing.
Estimate the root(s) by stating which two numbers the zero is between.
