My graph is'nt really looking right so just wondering if you guys get the same points i do:
y=2x^2-4x-1
And of course we are asked to fill in the x/y grid and plot the graph - so we have to put in -1 to the equation and +1 as x's value - just wondering what two numbers you get? I got -3 and 3?

John had a full deck of cards including two Jokers. He dealt Linda five cards: The ace of spades, the ten of hearts, the six of clubs, the five of diamonds, and one of the Jokers. He dealt himself the King of Diamonds, the five and six of clubs, and the two and three of spades. Question: What are the odds if each draws three cards that Linda will beat John by drawing another Ace when John does not improve over his pair of Kings?
