Answer:
d, b , a
Explanation:
Diagram on left
As x → + ∞, y → + ∞, as x → - ∞ , y → - ∞ ( as explained in previous question ) d
Top diagram on right
As x → + ∞, y → 0 and x → - ∞ , y → 0
This means that as x increases to the right , y approaches the x- axis (y → 0)
and as x increases to the left, y approaches the x- axis (y → 0 ) b
Lower diagram on right
As x → + ∞, y → + ∞ and as x → - ∞, y approaches the x- axis (y → 0 ) a
