Answer

Explanation:

Step1: Find the derivative of g(x)

$g'(x)=16x^{3}-6x^{2}-16x + 5$

Step2: Use a graphing calculator

Use ALEKS graphing calculator to find the roots of $g'(x)$ (critical - points). These are the values of $x$ where $g'(x)=0$.

Step3: Determine local maxima

Test the intervals around the critical - points using the first - derivative test or the second - derivative test. On the ALEKS graphing calculator, graph $y = g(x)$ and $y = g'(x)$ and identify the $x$ values where the function changes from increasing to decreasing (local maxima). Then find the corresponding $g(x)$ values.

Answer:

Since this problem requires using the ALEKS graphing calculator, the specific numerical answer cannot be provided without actually using the calculator. But the general steps to find the points $(x,g(x))$ where there is a local maximum are as above.
