Answer:
Derivative of i is y' =1 - [tex]\frac{1}{x^{2} }[/tex]
As for the second function, I'm confused by what you typed please retype it correctly so I can solve
Step-by-step explanation:
Work for the first derivative:
i. y = x - (1/x) = x - [tex]x^{-1}[/tex]
y' = [tex]x^{1-1} = x^{0} = 1\\\\\\x^{-1-1} =x^{-2} = \frac{1}{x^{2} }[/tex]
y' = [tex]1 -\frac{1}{x^{2} }[/tex]
