QUADRATIC FUNCTIONS – SCRATCH

1. Edit the code at mit.edu/projects/171546004/#editor (shown at right) to plot the quadratic function y = ax2. Sample output shown below.

 

2. Write to explain the effect of changing the value of a in y = ax2. Sketch and label illustrative graphs, and refer to them in your explanation.

 

3. Edit your code to plot y = ax2 + k. Sample output shown below.

 

4. Write to explain the effect of changing the value of k in y = ax2 + k. Sketch and label illustrative graphs, and refer to them in your explanation.

 

5. Edit your code to plot y = a(x – h)2 + k. Sample output shown below.

 

6. Write to explain the effect of changing the value of h in y = a(x – h)2 + k. Sketch and label illustrative graphs, and refer to them in your explanation.
