y = 2x^2 - 12x + 46

Compare your equation with the standard form of the equation:

y = ax^2 + bx + c

For your equation, a = 2, b = -12, c = 46.

The vertex has x-coordinate -b/(2a).

The x-coordinate of the vertex is: -(-12)/(2 * 2) = 12/4 = 3

Now we plug in x = 3 into the function to find the y-coordinate of the vertex.

y = 2(3^2) - 12(3) + 46

y = 2(9) - 36 + 46

y = 18 - 36 + 46

y = 28

The vertex is (3, 28)

Gala2k [10]

To find the probability of Joseph picking a key lime piece of taffy you will create a fraction with the number of possible outcomes over the total possible outcomes.

# of key lime taffies 12
total # of taffies = 60

12/60 = 1/5

1/5 = 0.2

Joseph has a 0.2 probability of picking a key lime taffy.
