d/(dy)(x-y)

Solution

\frac{d}{d y} (x - y)

- 1

Solution steps

\frac{d}{d y} (x - y)

Treat

x

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d x}{d y} - \frac{d y}{d y}

\frac{d x}{d y} = 0

\frac{d y}{d y} = 1

= 0 - 1

Simplify

= - 1

f^{^{''}} (x) = 4, f^{^{'}} (2) = 10, f (2) = 15
