HEL The vertex form of a quadratic function is f(x) = a(x – h)2 + k. What is the vertex of each function ? Match the
function rule with the coordinates of its vertex.
f(x) = 5(x - 6)2 + 9
(5.-9)
f(x) = 9(x - 5)2 + 6
(-5, -6)
f(x) = 6(x + 9)2 - 5
DO000
(6,9)
f(x) = 9(x + 5)2 - 6
(-9,-5)
f(x) = 6(x - 5) - 9

Afriend of mine is giving a dinner party. his current wine supply includes 10 bottles of zinfandel, 8 of merlot, and 11 of cabernet (he only drinks red wine), all from different wineries. (a) if he wants to serve 3 bottles of zinfandel and serving order is important, how many ways are there to do this? ways (b) if 6 bottles of wine are to be randomly selected from the 29 for serving, how many ways are there to do this? ways (c) if 6 bottles are randomly selected, how many ways are there to obtain two bottles of each variety? ways (d) if 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen? (round your answer to three decimal places.) (e) if 6 bottles are randomly selected, what is the probability that all of them are the same variety? (round your answer to three decimal places.)
