a) Create a class called 'PlayingCard' that does the following: • Has a constructor which creates the card - it should have a valid suit and a value. • You should have getters only for these values. • Note: use constants for suits and think of how you can constrain the value. Hint: You can use constants or enums. • Override the toString method to print the playing card like "8 ?" or "K" (static). (Hint: google 'unicode character for diamond') • Bonus: Print an ASCII Art version of the Card to the a print screen like the following: printAsciiCard(PlayingCard playingCard, PrintStream printStream) b) Create a class called "PlayingCardFactory" that has the following methods: • Generate Random Card (static) • Generate Random Card from a suit (static) c) Create a class called 'CardDeck' that has the following methods: • Has an ArrayList of Playing cards • Starts with a full deck of cards • Can be shuffled • Can draw a card • Create an application with a menu that let's you a) draw a card b) draw a hand c) print the deck, d) shuffle the deck and e) print out the deck

Consider the following quadratic function. f(x) = -2x\textsuperscript{2} + 8x - 11 (a) Write the equation in the form f(x) = a(x - h)\textsuperscript{2} + k. Then give the vertex of its graph. Writing in the form specified: f(x) = Vertex: (b) Graph the function. To do this, plot five points on the graph of the function: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.
