Answer:

P = 2x + 2y + 8

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

P = 2(l + w) ← l is length and w is width , then

P = 2(x + 5 + y - 1) ← distribute parenthesis

  = 2x + 10 + 2y - 2 ← collect like terms

  = 2x + 2y + 8

From x = -2 to x = 0, it's decreasing.

Then it's increasing again from x = 0 to x = 2, then decreasing after x = 2

So answer is the last one
It is increasing before x = -2 and from x = 0 to x = 2
