Graphing a Parabola

Positive means that the parabola faces up. Three make the parabola narrower than the original one. h=-1 make the parabola go left one unit. k=-1 make the parabola shift down one unit.

l used the same mathematical idea in three different ways: l can express the function by the graph above. l solve the equation by using in the values of a, h, k. l can also explain the equation by using mathematical vocabulary to demonstrate my understanding by the text above. l can prove l used formatting to share the information in a clear and organized way by the math equation listed above.
