Presentation on theme: "Anatomy of a Quadratic Function. Quadratic Form Any function that can be written in the form Ax 2 +Bx+C where a is not equal to zero. You have already."— Presentation transcript:
Warm Up! Complete this problem at the bottom of your sheet Solve 4x 2 +5=20
Solving using the Calculator Quadratic formulas can have more than one solution Because a square root of a number can give a positive and negative number They can also have no solutions, or just one
So how do I know if I am right? Use your calculator Solve so the entire equation is set equal to 0 Go to y= on your calculator Plug the equation into y1 Look for the x intercepts of the graph Use the Solve key to find values
Pythagorean Theorem a 2 + b 2 =c 2 Works only for right triangles What is a right triangle?
