Week 9 – Equivalent Forms of the Equation of a Quadratic Function

This week I learned the equivalent forms of the equation for a quadratic function.

Here is a common question:

This question asked me do each pair of equations represent the same quadratic function. I checked if they were the same by changing the equation in general form to standard form. To change the equation you need to factor by completing the square like we did in the last unit. The equations were then the same, so I knew they represented the same quadratic function.
