A function is given fx x3 2x Find the local maximum and mi

A function is given. f(x) = x^3 - 2x Find the local maximum and minimum values of the function and the value of x at which each occurs. State each answer rounded to two decimal places, local maximum (x, y) = local minimum (x, y) = Find the intervals on which the function is Increasing and on which the function Is decreasing. State each answer rounded to two decimal places. (Enter your answers using interval notation.) increasing decreasing

Solution

a.f(x)=x^3 -2x

To check the maximum and minimum points,we have to graph it

From the graph we can say that the graph is maximum at -0(.816,1.089) and minimum at (0.816,-1.089)
