Scarlett is trying to model a city's electricity usage throughout the day with a piecewise function. She has come up with a few options. Which of these options correctly models the graph to the left?

• f(x) = { x  if x < 4;   -x+1  if x ≥ 4

• f(x) = { x  if x ≤ 4;  -x+1  if x > 4

• f(x) = { -x+1  if x < 4;  x  if x ≥ 4

• f(x) = { -x+1  if x ≤ 4;  x if x > 4

Oliver, Ethan, and Mason are working on a project to decipher a coded message from an ancient artifact. They come across a mysterious piecewise function. They believe that solving this could reveal the secret message. Help them in evaluating the piecewise function for f(2). Remember, only type the number in the answer.

Aria, Avery, and Priya are on a treasure hunt in an old mansion. They come across a mysterious scroll with a piecewise function. The scroll guides them to find the value of f(0) to uncover the hidden treasure. Can you help them solve it? Remember, only type the number in the answer.

Mason, Oliver, and Benjamin are on a quest to find a secret code. They came across a mysterious piece of paper with a piecewise function, and they need to evaluate it for f(3) to unlock the next hint. Can you help them in solving it? Remember, only type the number in the answer.

Elijah, James, and Abigail are planning a treasure hunt. They find an old pirate map with a series of numbers. They deduce that these numbers represent the greatest integer function. Can you assist them in understanding how this function is depicted graphically?
