Answer on Calculus Question for hsd
For each of the following intervals, tell whether f(x) is increasing (input INC ) or decreasing (type in DEC ).
Note that this function has no inflection points, but we can still consider its concavity. For each of the following intervals, tell whether f(x) is concave up (input CU ) or concave down (type in CD ).
x not=A so f DEC on the both (−∞,A), (A,∞):
f"=72/(3x+2)^3x belongs (−∞,A) f"<0 then CU
x belongs (A,∞) f">0 then CD
