Practice problem
Determine the interval(s) on which the function is concave up and concave down
f(x)=−2(x+3)3+1f(x)=-2(x+3)^3+1f(x)=−2(x+3)3+1
Concave up x<−3x<-3x<−3
Concave up x>−3x>-3x>−3
Concave up (−∞,∞)(-\infty,\infty)(−∞,∞)
Concave down x<−3x<-3x<−3
Concave down x>−3x>-3x>−3
Concave down (−∞,∞)(-\infty,\infty)(−∞,∞)
Type a concept, like “slope” or “photosynthesis”.
