**My answer:** ((3/2) third(sqrt(x^2)) - (1/2))/x

I used the quotient rule for this because I didn't know how to use the Power Rule and the Sum and Difference rules to find the derivative of it.

**2.** Use the quotient rule to find the derivative.

y= (thirdsqrt(x^2))/(2sqrt(x)) , Get f'(-1)

**My answer: **DNE

**Derivative: **((1/3)x^(1/6))/(4x)

**Note:** thirdsqrt is the little three thing with the sqaure root. Eg. thirdsqrt(27) = 3
