Question

f(x) = 1/(sqrt[x+2]); find f'(a) ?

Answer 1

stuck at -(sqrt[x+2])/(x+2)

Answer 2

(1)/(~(x+2))

Add 0 to 1 to get 1.
(d)/(dx) x+2=1

Multiply the rational expressions to get -(1)/(2(x+2)^((3)/(2))).
(d)/(dx) (1)/((x+2)^((1)/(2)))=-(1)/(2(x+2)^((3)/(2)))

The derivative of (1)/((~(x+2))) is -(1)/(2(x+2)^((3)/(2))).
-(1)/(2(x+2)^((3)/(2)))

Answer 3
