Answer:
( 
, 0) and (8, 
)
Step-by-step explanation:
Curve is concave downward when the second derivative is negative.
y' = 
, by the Fundamental Theorem of Calculus
y'' = 
, which has a denominator that is always positive. The numerator 
is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.
