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. 

10-1 = 9 dimes and nickels

0.90 - 0.25 = 0.65 worth

N + d = 9

N=9-d

0.05N + 0.10D = 0.65

0.05(9-d) +0.10d = 0.65

0.45 - 0.05d +0.1d = 0.65

0.45 +0.05d = 0.65

0.05d = 0.20

d = 0.20/0.05

d = 4

 4 dimes and 5 nickels
