Question

Use a graphic calculator to determine the intervals on which (x)=2x^3-3x-1 is increasing or decreasing.

Answer 1

Answer:

im not sure of the answer but hopefully this will help

Step-by-step explanation:

basically the intervals in which its increasing and decreasing depend on the leading coefficient and the vertex

since this is opening up, the intervals will be

the function is increasing (x coord of vertex, infinity)

the function is decreasing (-infinity, x-coord of vertex)
