The function fff is given in three equivalent forms. Which form most quickly reveals the vertex? Choose 1 Choose 1 (Choice A, Checked)

A

f(x)=-3x^2+12x+15f(x)=−3x

2

+12x+15f, left parenthesis, x, right parenthesis, equals, minus, 3, x, squared, plus, 12, x, plus, 15

(Choice B)

B

f(x)=-3(x-2)^2+27f(x)=−3(x−2)

2

+27f, left parenthesis, x, right parenthesis, equals, minus, 3, left parenthesis, x, minus, 2, right parenthesis, squared, plus, 27

(Choice C)

C

f(x)=-3(x+1)(x-5)f(x)=−3(x+1)(x−5)f , left parenthesis, x, right parenthesis, equals, minus, 3, left parenthesis, x, plus, 1, right parenthesis, left parenthesis, x, minus, 5, right parenthesis

What is the vertex?

Vertex = ((left parenthesis

,,comma

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
