Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The derivative of a constant times a function is the constant times the derivative of the function.
Differentiate term by term:
Apply the power rule: goes to
The derivative of the constant is zero.
The result is:
So, the result is:
The result of the chain rule is:
Now simplify:
The answer is:
/ ___ _______\ |\/ 2 *\/ y - 2 | |---------------| \ 2 / ----------------- 2*(y - 2)
___ -\/ 2 ------------- 3/2 8*(-2 + y)
