The turning point is always going to be the minimum or the maximum. The turning point is your vertex. Since there appears to be a lowest y value, the graph probably doesn't have a highest y value. It depends a little on the question. The vertex is where the graph turns.Explore math with our beautiful, free online graphing calculator.

Step 1.8.2 Substitute the known values of and into the formula and simplify.Shifting parabolas. The 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.
