8-3 Vertical Translation of a Parabola
Experiment with the interactive below to see how the value of a impacts the graph of the parabola defined by y = ax^2 + c. Use the slider to adjust the value of c and watch the graph to see how it changes. What does the graph look like when c is positive? What does it look like when c is negative? How does the graph of the parabola change for larger or small values of c?
