X and Y intercepts ( Zeros ) "y = a(x-h)^(2) + k" is the equation used to solve the vertex form problems. Si el coeficiente del término x 2 es positivo, el vértice será el punto más bajo en la gráfica, el punto en la parte baja de la forma “U”. The last two easy transformations involve flipping functions upside down (flipping them around the x-axis), and mirroring them in the y-axis.

These parabolas open towards the left or right 5 x=a(y-k) 2 +h 6 x=(y-k) 2. 1 We can set y=0 and solve for x:. The simplest Quadratic Equation is:.
