Click For Summary
To find the derivative of 4f(x) at x = 6, one must first determine f'(x). The discussion indicates that g'(x) was found to be -1, which suggests a relationship between g(x) and f(x). The slope of the f(x) graph at x = 6 is sought, implying that understanding f'(x) is crucial. Clarification on the calculations for f(x) and its derivative is requested. The conversation emphasizes the importance of deriving f(x) from the known g(x).

What is the slope of the f(x) graph at x = 6? If you could do g(x) you can certainly do f(x)...

Edit: And g'(6) = -1, by the way.
