Solve It! Last season, you made 40% of your basketball shots. The Game 1 shot chart shows that you did not start the season so well.

Starting with Game 2, how many consecutive shots must you make to raise this season's percentage to 40%?

Solve It! Last season, you made 40% of your basketball shots. The Game 1 shot chart shows that you did not start the season so well.

If you never miss another shot this season, is it possible to raise your percentage to 99%? 100%? Explain your reasoning.

Problem 4 Got It? What is the graph of the rational function?

Use the techniques you've learned to graph the function by hand using the blue pen tool. Include all relevant graph detail.
Graph the function using Desmos' graphing calculator and copy that graph to yours using the orange pen tool. It is alright if the graphs overlap in some places and are different in others.
Note any discrepancies between the graph you created by hand and the precise Desmos graph.

Problem 5 Got It? You want to mix a 10% orange juice drink with 100% pure orange juice to make a 40% orange juice drink. The function below gives the concentration y of orange juice in the drink after you add x gallons of the 10% drink to 2 gallons of pure juice.
How much of the 10% drink must you add to get a drink that is 40% juice?
You may use Desmos or the embedded Desmos graphing utility above.

Problem 5 Got It? Reasoning: If you wanted a drink that is 80% orange juice, would you need to add half as much as your answer in the previous item?
