1.) Standard (Vertex) Form: y = a (x-p)²+ q
We can find the vertex
2.) General Form: y = ax² + bx + c
You can find the Y-intercepts
3.) Factored Form: y = a ( x – x1 ) (x – y2 )
You can find the X-intercepts
We also learned how parent functions transform . Here we have the vertex form y = a (x-p)²+ q
in the equation will tell us if the parabola opens down or up, and if there’s a stretch or a compression. the p will tell us if there’s a horizontal translation and the q will tell us if there’s a vertical translation.
