How do you find the derivative of
$\sqrt{x^2 - 4x + 4}$
I applied Chain rule and got this
$\frac{x-2}{\sqrt{(x-2)^2}}$
However, the fill-in box requires two distinct functions (piecewise) where x > ______ and x < _____.
How would I get two equations from the derivative?
Answer
Hint: $\sqrt{x^2-4x+4}=\sqrt{(x-2)^2}=|x-2|$
