If you look at the graph you can tell the graph is increasing before x = -2.
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
X^8 = ()^2
x^8 = (x^4)^2
x^8 = x^8
inside the parethesis is x^4
hope this helps
