This is a quadratic function that we will change into a parent function then graph. After finding the parent function (shown in the 2nd picture), it will help us find our vertex, x-intercept, axis, and x-intercept(s). The problem is color coded to show you were the numbers came from in the problem.
The viewer needs to remember to use (b/2)^2 when completing the square in order to find the x-intercepts. It is a crucial part of the problem that needs to be added to both sides of the equal sign. When doing the problem, the viewer needs to plug the point into their graphing calculator in order to find their approximated points. They need to trace their left and right bound before the calculator guesses.
