Suppose that f(x)=14x−6x3. (a) find the average of the x values of all local maxima of f. note: if there are no local maxima, enter -1000.

Maximum at

Step-by-step explanation:

Given function,

Differentiating with respect to x,

For critical values :

Now, differentiating equation (1) again with respect to x,

Since,

This means that the function is maximum at

While,

This means that the function is minimum at
