Answer:

f(1) = 4

Step-by-step explanation:

f(1) means let x=1 and find the y value at that point on the graph

At x=1 there is an open circle and a closed circle. The open circle means that the function does not have a value at that point, so we use the closed circle

f(1) = 4

Answer:

5 rolls

Step-by-step explanation:

The perimeter lengths are the same because it's a square. So 12 times 4 is 48. You would need a minimum of 5 rolls because each roll as a length of paper of 10 feet. So 40 feet plus 8 would round to 50. That's why it would be 5 rolls.
