Hey no worries, Mark44, beside I found my version of the solution completely out of luck just bored and messing around with my calculator :P
You're version of the sum of two terms is just as valid isn't it?
It only works with odd numbers
(√1.5 + √3.5)2 + (√1.5 + √3.5)2 = (√3 + √7)2
The left side is 2 * 9.58 = 19.16. The right side is 19.16(√44.5 + √6.5)2 + (√44.5 + √6.5)2 = (√89 + √13)2
The left side is 2 * 85.014 = 170.029. The right side is 170.029
yesh?
Hey forum I got to submit this in a few hours so if anyone could help me with this quick times, you would really be saving me :P
Homework Statement
Given the following graph of h(x)
I only need help with part b)
which asks for the local minimum or maximum points of the graph...
3[√3+√5+√7]^2
3[√(1.5)+√(2.5)+√(3.5)]^2 + 3[√(1.5)+√(2.5)+√(3.5)]^2
up in the middle of the night doing this.. so I may have broken a million rules getting to this point :blushing:
You Might want to double check but they seem equivalent :devil:
Thanks! okay that makes a lot of sense actually :D
SO its one or the other, right?
How do I prove whether its constantly increasing or decreasing using derivatives?
cuz normally I would equate the derivative to zero.. take the values that gives me for x..
and consider those 'significant...

hey Forum! I had a question here I'm struggling with and was wondering if someone could take a look. its Dealing with calculus, specifically derivatives and behaviors of the graph:

I just started and part a) already has me stumped D...
Hey forum, I know this is an easy one, but it's been a while for me :P
thanks for your help!
Homework Statement
Given the following graph of h(x)
a) The intervals where h(x) is increasing and decreasing
b) The local maximum and minimum points of h(x)
c) The intervals where h(x) is...
yes thank you SammyS :) so far I'm at caught up with you to this point
so I'm thinking that g'(x) = 11/(x^2+8x+16
is a better answer than
g’(x) =2(x + 4)^(-1) – (2x – 3)(x + 4)^(-2)
yes?
Also any thoughts on my second derivative answer?g’’(x) = -2(x + 4)^(-2) – 2(x + 4)^(-2) +(–4x + 6)(x +...
oh wow okay.. I just worked my answer of g’(x) =2(x + 4)^(-1) – (2x – 3)(x + 4)^(-2)
through and got the same answer of g'(x) = 11/(x^2+8x+16)
I see what you mean!
so is the second answer (in red) better than my other answer? obviously they are equivalent but you can see I got mine from using...

Hey forum, hope everyone is having a good day!
If someone could check this question out for me that'd be great!
Determine the first and second derivative:
g(x) = (2x - 3)/(x + 4)
The Attempt at a Solution
g(x) = (2x – 3)(x + 4)^(-1)
g’(x) = (2x – 3)’(x +...
