The graph of f (x) = RootIndex 3 StartRoot x + 8 EndRoot is shown. On a coordinate plane, a cube root function goes through (negative 16, negative 2), has an inflectio point at (negative 8, 0), and goes through (0, 2). Which statement is true?

The function is always increasing.
Step-by-step explanation:
The function is only increasing when x ≥ −8.
The function is only increasing when x ≥ 0.
The function is always decreasing.
The function is always increasing.
f(x) = ∛(x + 8)
inflection point (-8 , 0)
passes through (0 , 2)
x f(x)
-20 -2.289
-16 -2
-12 -1.587
-8 0
-4 1.587
0 2
8 2.519
12 2.714
16 2.884
19 3
from graph its very clear that
f(x) is always increasing
