Question

what is the outside function in
y=[(ln(3z))^2] ? for chain rule

Answer 1

squaring

Answer 2

^2 then ln(3z)

Answer 3

the squaring funcion
\[S(x)=x^2\] because that is the last thing you would do if you were evaluating this for a specific value of x

Answer 4

so the inside would be ln(3z)?

Answer 5

1) multiply by 3
2) take the log
3) square

Answer 6

no. 3z

Answer 7

so this is a composition of three functions in that order

Answer 8

sorry i meant then ln then 3z

Answer 9

so how would you write this exactly?

Answer 10

y=[ln(3z)]^2
dy = 2ln(3z)(1/3z)(3)

Answer 11

still confused
