Max/Min of Polynomial Function

Click For Summary
SUMMARY

The discussion focuses on determining the equation of the tangent line to the polynomial function f(x) = 4x³ + 12x² - 96x with the smallest slope within the interval -4 ≤ x ≤ 2. Participants emphasize the importance of finding the derivative, identifying critical numbers, and evaluating these points to ascertain maximum and minimum slopes. The process involves calculating the first derivative, setting it to zero to find critical points, and then evaluating the original function at these points to determine the minimum slope.

The question is:

Determine the equation of the line tangent to f(x)=4x^3+12x^2-96x wit hthe smallest slope on the interval -4 <= x <= 2.

So I found the derivative and critical numbers to find the max and min but where do I go from there?

So you need to find the line with minimum slope. What function gives you the slope? How do you find extremes of a function?
 
By finding the critical numbers of the derivative and plugging them into the original function, as well as the intervals and finding the lowest number would be the minimum value.
