The graph of f(x)= power of 3√x + 8 is shown.

which statement is true?

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.

Based on the graph, the true statement is : THE FUNCTION IS ALWAYS INCREASING.

when x = -16 ; y = -2
when x = -12 ; y = -1.5
when x = -8 ; y = 0
when x = -6 ; y = 1.25
when x = 0 ; y = 2
when x = 6 ; y = 2.5

As the value of x increases, so does the value of y. Thus, the function is always increasing. 

Y’all got to do it all over
