The best prediction is
(C) x → ∞, f(x) → –∞, and as x → –∞, f(x) → ∞.
An interval is a set of real numbers between two given numbers called the endpoints of the interval.
Given:
x f(x)
-4 18
-3 9
-2 6
-1 3
0 0
1 -3
2 -6
3 -9
4 -18
As, from the table x increases, the value of f(x) decreases
i.e. Over time, when x → ∞, f(x) → –∞
and then x decrease, the value of f(x) increases
when x → –∞, f(x) → ∞.
Hence, best predicts the end behavior of the graph of f(x) is x → ∞, f(x) → –∞, and as x → –∞, f(x) → ∞.
