The x-values where y>0,y<0 and y=0 for the function y=6+x3115x5 using the graph:

Mathematical Applications for the Management, Life, and Social Sciences, Chapter 10.1, Problem 23E

Explanation

Given Information:

The provided function is y=6+x3115x5.

Explanation:

The critical values are the only values at which the graph can have turning points, the derivative cannot change sign anywhere except at the critical value.

This, in an interval between two critical values, the sign of the derivative at any value in the interval will be the sign of the derivative at all values in the interval.

As per the First Derivative Test,

The first derivative of the function is evaluated. The first derivative is made equal to zero in order to get the critical points.

The values of the critical values are kept inside the original function which gives the critical points. The intervals of the values of x are then evaluated for the relative maximum and minimum.

To obtain the relative maxima and minima of a function,

1. Find the first derivative of the function.

2. Set the derivative equal to 0 to obtain the critical points.

3. Evaluate f(x) at values of x to the left and one to the right of each critical point to develop a sign diagram.

(a) If f(x)>0 to the left and f(x)<0 to the right of the critical value, the critical point is a relative maximum point

(b)

To determine

To calculate: The conclusions from the derivative where the function y=6+x3115x5.
