Determine where the graph of the function is concave upward and where it is concave downward. (Enter your answers using interval notation. If the answer cannot be expressed as an interval, enter EMPTY or ∅.)

g(x) = 2x^{3} − 4x

Step 1

Given, function

Step 2

In order to finding concave up and concave down, first finding the inflection points.

Inflection points are find using second derivative of function equal to zero.

Step 3

For inflection...
