Hope this helps : )*****
<span>f '(x) = 6/(x^1/3) + 3 = 0
x = -8
Observe that f '(-7) > 0 and f '(-9) < 0. Therefore, we have a relative min at x = -8.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Answer:
5h+6=16
Step-by-step explanation:
He gets 6 dollars and for every hour he walks he gets 5 dollars so he must of walked dogs for 2 hours and plug it in you get your equation.
Composing functions just means to feed the ouput of the inner one as the input for the outer one.
So, the following writings are equivalent:
Using the second form, we can see that the first thing to do is to compute 
, which is given:
This means that we can update the fomula:
So, now we have to compute 
. Given 
, we know that 
doubles the input and adds one. In this case, the input is 
, so we have to double this and add one:
So, we have
Similarly, from 
, we understand that 
just adds 3 to the input. In this case, the input is 
, so we'll add 3 to this quantity:
So, we finally have
