**QUADRATIC FUNCTIONS – PYTHON**

** 1.** Try the code below at cemc.uwaterloo.ca/console. The expected output is shown at right.

a) Edit the code to also print differences between successive y-values.

b) What pattern emerges?

c) What is the sum of the first 5 odd numbers? The first 10?

**2.** Predict: What will the graph of **(x, y)** pairs for the above data look like? Plot **(x, y)** pairs on the grid to check.

**3.** What would be the output of the code at right? How would it differ from #1 above? Try it at cemc.uwaterloo.ca/console. Plot the **(x, y)** pairs on the grid below.

**4.** Record your prediction of the output for each code block below. Test at cemc.uwaterloo.ca/console.

**5.** Predict the shape of the graphs in 4.a) and 4.b) by studying the equations used in the code. Check by plotting the **(x , y)** pairs on the grids below.

**6.** Write Python code whose **(x, y)** output would match the graph below. Test your code at cemc.uwaterloo.ca/console. Does the **(x, y)** output match the graph?
