Which describes the end behavior of the polynomial function?

(graph below)

a.) as x→±∞, f(x)→1
b.) as x→-∞, f(x)→8, and as x→∞, f(x)→8
c.) as x→+∞, f(x)→-∞, and as x→-∞, f(x)→+∞
d.) as x→+∞, f(x)→+∞, and as x→-∞, f(x)→-∞

As x→+∞, f(x)→+∞, and as x→-∞, f(x)→-∞

Step-by-step explanation:

From the gragh it is clear as x tend to +∞, the f(x) tends to +∞.

And as x tends to -∞, f(x) tends to -∞.

Therefore, x→+∞, f(x)→+∞, and as x→-∞, f(x)→-∞

answer: 1, 3 and 5 are correct
