This problem is about changing an equation from standard from into parent function form so that it is easier to graph. In this problem, you are trying to find the vertex, x-intercepts, y-intercept, and the axis of symmetry. Multiple steps are necessary to finding the solution. These steps will ultimately make graphing the equation easier and more accurate.
In order to understand, special attention should be given to finding the vertex. We must remember that h is the opposite of its sign in the parent function. Additionally, it is necessary to recall that the x-intercepts may have 1, 2 or none (imaginary) x-intercepts. Also, to better understand, we must also recognize that the parent function allows us to provide an accurate representation of the function.
