Question

if f(x)=3x-11ln(8x) on the interval [1,7], what is the absolute maximum and the absolute minimum?

Answer 1

First step: Solve \(f'(x)=0\) to find critical points.

Answer 2

how do I find f'(x) for this function?

Answer 3

Derive the function. Basic application of the chain rule, just remember that if \(f(x)=\ln x\), then \(f'(x)=\frac{1}{x}\).

Answer 4

got it thank you!
