What is the change that occurs to the parent function f(x) = x2 given the function f(x) = (x - 3)2. A.)Graph moves 3 units down.

  D.)  Graph moves 3 units right.

Step-by-step explanation:

Replacing x with x-h moves the graph h units to the right. Here, h=3, so the graph is moved 3 units to the right.

  parent: f(x) = x^2

  translated: f(x) = (x -3)^2

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.
