okay.. I know the quadratic formula and I can get to the point where x= sqrt(3)x +- sqrt(2bx-5)= 0 I still don't know what to do from here. HOW CAN I FIND VALUES B TO GET A local MAX MIN??!?

f'(x) = 3x^2 - 2bx + 5 = 0 ^Keep the B right?? Well I did manage to get this far when I attempted this problem but I have no idea what to do next or if I even got the differential right. Will the variable 'b' be equal to 0 when you differentiate thus negating -2bx or will...

Hi everyone, I have no clue on how to solve this one. Can anyone help me out? Determine all values 'b' for which the functioln f(x) = x^3 - bx^2 + 5x + 7 will achieve local minimum and maximum values. Thanks~

I am working on a couple of problems for my calc class, and I was wondering if the answer I got for the rate of horizontal change in problem 1 is correct and if the answers I got in problem 2 are correct. ========Problem 1========= A winch at the top of a 12-meter building pulls a pipe of the...

Hi, I'm having trouble figuring out a few problems from my assignment. If anyone can offer some help I'd be grateful :) 1. For each part of problem, either give fromulas and graphs of functions F and G satisfying the given conditions or carefully explain why it is impossible to find functions...
