Find direction of parabola
WebThe graph of y=(x-k)²+h is the resulting of shifting (or translating) the graph of y=x², k units to the right and h units up. For example, y=(x-3)²-4 is the result of shifting y=x² 3 units to the right and -4 units up, which is the same as 4 units down. WebFor standard form: y=Ax^2+Bx+C. Look at the coefficient of the x^2 term. If "A" is positive, the parabola opens up. If "A" is negative, then the parabola opens down. For Vertex Form: y=a (x-h)^2+k. The sign of "a" determines …
