This problem is about demonstrating the process of establishing a parent function equation with a standard form to begin with. The vertex, x-intercepts, y-intercepts, and axis is to be found. To make a graph the most efficient and accurate, these steps are necessary.
The viewer needs to recognize to (x-h) in the parent function equation. The parent function equation is y=a(x-h)^2+k. To graph the x-point of the vertex, you need to know that h is opposite of what it appears to be. For example (5-2)^2. That (-2) would be 2 when you graph it. Another thing you must acknowledge is that the x-intercepts may include imaginary numbers, and when that happens you cannot graph it since it is imaginary for the x-intercepts.
