Question

Determine the inflection points and intervals of concavity for the function $f (x) = 3 \sin x + 2 x^{2}$ , $negative 2 pi is less than or equal to x is less than or equal to pi$ .

Accepted Answer

Inflection point: None

Concave up on $\left\lbrack-2\pi,\pi\right\rbrack$

Answer

Inflection point: $f (x) = 3 \sin x + 2 x^{2}$
