Practice problem
Determine the interval(s) on which the function is concave up and concave down
f(x)=−x−63f(x)=\sqrt[3]{-x-6}f(x)=3−x−6
Concave up x<6
Concave up x>6
Concave up (−∞,∞)(-\infty,\infty)(−∞,∞)
Concave down x<6
Concave down x>6
Concave down (−∞,∞)(-\infty,\infty)(−∞,∞)
Type a concept, like “slope” or “photosynthesis”.
